'''Arbiter Thel 'Vadam''' (formerly ''''Vadamee'''){{Ref/Marketing|Id=LongRoad|Halo Waypoint|The Long Road Home}} is the [[Sangheili]] [[kaidon]] of the [[House of 'Vadam]] and the last [[Arbiter]] to serve the [[Covenant]]. He continues to hold this title in the [[Post-Covenant War conflicts|wake]] of its [[Great Schism|dissolution]]. Presently, he leads the [[Swords of Sanghelios]], an alliance of [[keep]]s modeled after an ancient order of the same name, and is considered by many to be the formal leader of all Sangheili as the '''Kaidon of Unity'''.<ref name="wp thel">[https://www.halowaypoint.com/en-us/universe/characters/arbiter-thel-vadam '''Halo Waypoint''': ''Arbiter Thel 'Vadam'']</ref>{{Ref/Book|Id=Enc22P245|Enc22|Page=245}}

Thel commanded several fleets during his service in the [[Covenant]], most notably the [[Fleet of Particular Justice]], of which he was [[Supreme Commander]]. This fleet mounted a successful [[Fall of Reach|attack]] on the [[human]] colony of [[Reach]] under his command and later [[Battle of Installation 04|fought]] the crew of the {{UNSCShip|Pillar of Autumn}} on [[Installation 04]], the first [[Halo Array|Halo ring]] to be discovered by the Covenant and [[humanity]]. 'Vadamee was responsible for over one billion [[human]] casualties over the course of the decades-long war against the humans and the [[glassing]] of at least seven colonies.<ref name="terminal 3">'''[[Halo 2: Anniversary]]''', ''[[Terminal (Halo 2: Anniversary)|Terminal 3]]''</ref> At the outbreak of the [[Great Schism]], Thel became a leading figure among the Sangheili and aided the [[United Nations Space Command]] in its efforts to stop the [[High Prophet of Truth]] and his forces from activating the [[Halo Array]]. He and [[Fleet of Retribution|many Sangheili]] fought in multiple battles alongside the [[Spartan-II]] super-soldier, [[John-117]] on [[Installation 05]], [[Earth]], and [[Installation 00]] in the final weeks of the war.

Returning to [[Sanghelios]] after the war's conclusion, Thel became a symbol of Sangheili honor and resilience in the face of betrayal. He attempted to unite the feudal states across his homeworld in forming the first coalition government since the [[War of Beginnings]]. Despite his efforts, he met resistance from [[Covenant remnants|other Sangheili factions]], who felt that his ideals and beliefs went against the traditional Sangheili values of [[Forerunner]] worship or that the peace treaty with the [[human]]s could not be trusted. This disagreement soon spilled over into [[Blooding Years|civil war]], and the Swords of Sanghelios became locked in conflict with other groups, primarily [[Jul 'Mdama's Covenant]] and the [[Servants of the Abiding Truth]]. He led the Swords to victory over these two groups, thanks in part to assistance from the UNSC.  

[[File:H2A Terminals ThelTraining.png|thumb|250px|Thel 'Vadamee training.]]

Thel was born to the noble and powerful [[House of 'Vadam]], rulers of the powerful state of [[Vadam]] on [[Sanghelios]]. In his youth, Thel was trained in the ways of fighting by his relative [[Lak 'Vadamee]].<ref name="tcp349">'''[[Halo: The Cole Protocol]]''', Chapter 72, ''page 349''</ref> He later joined the [[Covenant military]], adding the "-ee" suffix to his surname according to custom. During the [[Human-Covenant War]], Thel participated in the Covenant [[Fall of Madrigal|attack]] on the [[human]] [[Outer Colony]] of [[Madrigal]] in [[2528]].<ref>'''Halo: The Cole Protocol''', Chapter 19, ''pages 146 and 156''</ref> By [[2535]], he had at least one wife.{{Ref/Novel|Id=HTCP19|HTCP|Chapter=19}}

Within a short time, Thel achieved both the rank of [[Sangheili Zealot|Zealot]] and the title of [[shipmaster]], and became [[kaidon]] of his state through the votes of Vadam's [[elder]]s.<ref>'''Halo: The Cole Protocol''', Chapter 9, ''page 89''</ref> At some point, Thel would sustain an injury in the training ring due to a mistake. His family, having a recently promoted shipmaster in the bloodline, hushed up the incident, as well as the resultant visit by a physician, due to the Sangheili's cultural stigma toward doctors and medical operations. During his convalescence, Thel handmade an old-fashioned [[doarmir]]-fur shipmaster's cloak, and would later wear it as part of his shipmaster's attire to remind him that he could make grave mistakes if he let his guard down.<ref>'''Halo: The Cole Protocol''', Chapter 22, ''page 159''</ref> Thel's role as kaidon was important for the House of 'Vadam, as he was tasked with continuing the reign of the powerful state of Vadam. Early in his rule, he was attacked by three Sangheili assassins wielding energy swords. He managed to kill all three without injury, and proceeded to appear before Vadam's elders to determine which had ordered the attack. Thel discovered that the assassination orders had come from the elder [[Koida 'Vadam]], and after killing him, he ordered all of Koida's line to leave Vadam keep by sunrise.<ref>'''Halo: The Cole Protocol''', Chapter 8, ''pages 83-94''</ref>

[[File:H2A Terminals - ThelZealot.png|250px|thumb|left|Thel 'Vadamee as an Elite Zealot soldier]]

In [[2535]], Thel was sent to [[Charybdis IX]] with command over the vessel ''[[Retribution's Thunder]]'' to participate in the [[Battle of Charybdis IX]], while being overseen by the [[Prophet of Regret|High Prophet of Regret]]. He and several other Sangheili boarded the {{UNSCShip|Do You Feel Lucky?}} and attempted to access the vessel's navigation database, but it had already been purged. He left and witnessed the destruction of the ship before being called to ''[[Infinite Sacrifice]]'', where he met the Prophet of Regret in person. Regret informed him of humans reportedly wielding modified Covenant weapons, a transgression he believed to be the doing of the [[Kig-Yar]]. He was then sent to the [[23 Librae]] system to track down the source of the illegal weapons traders. For the mission, his ship was accompanied by the Kig-Yar vessel ''[[A Psalm Every Day]]'', commanded by Shipmistress [[Chur'R-Mut]] and the [[Jiralhanae]] [[Jiralhanae Chieftain|Chieftain]] [[Pellius]].<ref>'''Halo: The Cole Protocol''', Chapter 18, ''page 138-148''</ref><ref>'''Halo: The Cole Protocol''', Chapter 21, ''page 153''</ref>

Upon arriving at 23 Librae, Thel and his crew discovered the [[Rubble]], a collection of asteroid habitats built by Kig-Yar and Insurrectionist humans working together. Almost immediately afterward, ''Thunder'' was attacked by ''A Psalm Every Day''; Pellius had decided to betray Thel so that he could claim sole credit for the discovery. Thel and his crew were taken by surprise, allowing the traitorous vessel's second salvo to disable the ''Thunder's'' weapons, communications and engines. ''A Psalm Every Day'' escaped while Kig-Yar boarding craft and [[Dextro Xur-pattern Spirit|Spirit]]s strafed the hull. Thel, increasingly frustrated, gave permission for his crew to abandon ship; this was a test to weed out the weaker Sangheili among his crew. Enemy Spirits destroyed the retreating craft in short order. Thel then ordered the destruction of the ''Retribution's Thunder'', which killed the boarding Kig-Yar.<ref>'''Halo: The Cole Protocol''', Chapter 22, ''pages 155-163''</ref> Thel, however, survived and was captured, imprisoned on the Rubble along with most of the bridge crew. They ultimately managed to escape and hijack a [[Kig-Yar shuttle]],<ref>'''Halo: The Cole Protocol''', Chapter 24, ''pages 169-172''</ref><ref>'''Halo: The Cole Protocol''', Chapter 27, ''pages 187-190''</ref> taking them to [[Unnamed Kig-Yar transport|another Kig-Yar vessel]]. On the surface of [[Metisette]], Thel captured the leader of the warband, [[Reth]].<ref>'''Halo: The Cole Protocol''', Chapter 29, ''pages 194-203''</ref><ref>'''Halo: The Cole Protocol''', Chapter 32, ''pages 214-217''</ref>

[[File:H2A Terminals - Jai vs Thel.jpg|thumb|250px|'vadamee and Jai engaged in combat.]]

Thel managed to destroy most of the Rubble's [[mass driver]]s,<ref>'''Halo: The Cole Protocol''', Chapter 56, ''pages 299-301''</ref><ref>'''Halo: The Cole Protocol''', Chapter 60, ''page 310''</ref> but was left helpless when [[The Redoubt]] was destroyed and [[Habitat Exodus]] left the system. There was little else to do but wait for the [[Hierarchs|High Prophets]] of [[Prophet of Truth|Truth]] and [[Prophet of Regret|Regret]] to arrive and recover him with his comrade, [[Zhar (Sangheili)|Zhar]].<ref>'''Halo: The Cole Protocol''', Chapter 65, ''pages 329-330''</ref> Upon reporting the failure of the mission, Zhar attempted to kill the Prophets feeling helpless at the loss of his honor caused by the Prophet's scheming. Thel activated his [[Type-1 Energy Weapon/Sword|energy sword]] and killed his friend without mercy.<ref>'''Halo: The Cole Protocol''', Chapter 69, ''pages 340-342''</ref> This act prompted Truth to spare his life, and he gave Thel command over a ship in the [[Fleet of Particular Justice]].{{Ref/Reuse|tcp349}}

[[File:H2A Terminals - Thel and Prophet.jpg|thumb|left|250px|Thel 'Vadamee discovering Installation 04.]]

At some point between 2535 and 2552, Thel 'Vadamee served as the [[Supreme Commander]] of the [[Fleet of Particular Justice]]. During this time he led the Covenant forces in the [[Battle of Camber]]. 'Vadamee and his fleet caught the UNSC forces completely unaware. He began his ground and orbital assault before most of the planet was aware of the attack. While 17 of his ships bombarded key defensive positions, 'Vadamee personally led an attack on the UNSC system headquarters. He first engaged the [[3rd Battalion Reserves]], who were caught completely unprepared. 'Vadamee ordered his men to wait for the humans to prepare to defend themselves before wiping out the entire unit.<ref name="h2at2">'''Halo 2: Anniversary''', ''[[Terminal (Halo 2: Anniversary)|Terminal 2]]''</ref> Throughout his time as Supreme Commander he was also responsible for the glassing of [[Bounty]], [[Alluvion]], [[Mesa]], [[Greydowns]], [[Kroedis II]], and [[Estuary]]. He and his forces were responsible for over 1 billion human casualties—over 23,000 of them military personnel—and the destruction of 123 UNSC ships.{{Ref/Reuse|terminal 3}} ONI [[ONI#Section Three|Section 3]] attempted to kill him at different times, but failed each time resulting in the deaths of several operatives.<ref name="a2at1">'''Halo 2: Anniversary''', ''[[Terminal (Halo 2: Anniversary)|Terminal 1]]''</ref>

[[File:HGN ThelVadamee SupremeCommander.png|thumb|150px|'Vadamee wearing an ornate helmet and cloak during the [[Battle of Installation 04]].]]

Near the end of his time serving as Supreme Commander, he led the Covenant forces under his command to victory over the UNSC's greatest military stronghold. The [[Fall of Reach]] proved to be the highlight of Thel's service in the Covenant. As the battle ended, Thel ordered a flotilla of warships to follow the fleeing {{UNSCShip|Pillar of Autumn}}. The ''Autumn''<nowiki>'</nowiki>s course led them to holy Forerunner artifact [[Installation 04]]. After confirming that the ring was a creation of the "gods", the [[Prophet of Stewardship]], the highest ranking political figure with the Fleet, immediately claimed authority over the operation, claiming the mission was now a religious matter. As Thel was unwilling to relinquish command with the ''Pillar of Autumn'' en route, and unable to contact ''[[High Charity]]'' to determine who held jurisdiction, a power struggle emerged between Thel and Stewardship for ultimate authority. As the [[Battle of Installation 04]] wore on, the Prophet began subverting Thel, misappropriating military forces to secure facilities on the ring. Thel sent a single infantry unit to the ''[[Ascendant Justice]]'' to relieve the Prophet, but it was destroyed on approach. The Prophet threatened further punishment for any future affronts to his leadership. As Thel assembled a strike force to physically relieve the Prophet, the emergency beacon on the ''[[Infinite Succor]]'' was activated. Thel dispatched a [[Covenant Special Operations|Special Operations]] force to assess the threat and procure the [[Minister of Etiology]].<ref name="priority">''[[Halo: The Flood]]'' (2010), [[Halo: The Flood#2010 bonus content|Adjunct]] - [[Priority Broadcast Log/Eleventh Cycle, Third Unit]]</ref> As Thel was about to leave with his strike force for ''Ascendant Justice'', [[Special Operations Commander|Spec Ops Commander]] [[Rtas 'Vadum]]ee returned to the ship and revealed the results of his mission: the [[Flood]] had been unleashed on Halo.<ref>'''[[Halo Graphic Novel]]''', ''[[The Last Voyage of the Infinite Succor]]''</ref>

 

[[File:H2A-ThelBeforeHierarchs.jpg|thumb|left|250px|The Hierarchs of the High Council leading the trial of Thel 'Vadamee.]]

With the situation deteriorating, Thel ordered the evacuation of all ships from the ring, as well as shooting down any vessel which failed to return clean bioscans. When Thel's force arrived on ''Ascendant Justice'', he discovered that the Prophet of Stewardship had left for the ''[[Truth and Reconciliation]]''. The crew of the ''Ascendant Justice'' acknowledged Thel's authority as Supreme Commander without hesitation.{{Ref/Reuse|priority}} Unsurprisingly, Thel refused to come to the Steward's aid after its capture by the UNSC. These distractions were to cost Thel the battle, as SPARTAN-117 and Cortana successfully detonated, ''Pillar of Autumn'' under the nose of the Covenant's occupation. The detonation destroyed the Halo ring, ending the Battle of Installation 04. With little else to be done, Thel ordered his surviving ships to fall back from the destroyed Halo. This retreat was to save his remaining fleet from the Flood, but not his honor. In an act that further humiliated Thel, the ''Ascendant Justice'' was captured by [[John-117]] and a small human boarding party. Shortly after his ships failed to pursue the ''Ascendant Justice'', Thel was called before the Covenant High Council to answer for his failures.<ref>'''[[Halo: First Strike]]''', Epilogue, ''page 340''(2003 paperback); ''page 408''(2010 paperback)</ref>

 

During his time returning to High Charity, Thel wrote a ''[[Halo 2 Limited Collector's Edition Manual|Report on the Atrocity at Halo]]'', detailing his view and apology for the ring's destruction alongside an analysis of the weaponry and vehicles of both the Covenant and Human ground forces.<ref>''[[Halo 2 Limited Collector's Edition Manual]]''</ref>{{clear}}

[[File:H2A - Arbiter helmet.jpg|thumb|250px|'Vadamee wearing the Arbiter helmet for the first time.]]

{{Quote|Most high and honored Prophet: It is with greatest shame that I lay myself before the judgment of the Council. I expect and will accept no mercy. My failure in this matter is absolute; I embrace my responsibility and my punishment. <br>The disgrace and blasphemy at Halo was an abomination caused by my incompetence and failure of judgment.|'Vadamee to the Prophet of Truth in the ''Report on the Atrocity at Halo''.{{Ref/Book|[[Halo 2 Limited Collector's Edition Manual]]|Page=2}}}}

The loss of the holy [[Forerunner]] [[Installation 04|relic]] was an unforgivable failure in the eyes of the High Prophets and Sangheili Councilors. 'Vadamee was stripped of his rank, title, name, and honor, and branded a heretic for his failure to safeguard the Sacred Ring.{{Ref/Level|H2|[[The Heretic]]}} The [[Mark of Shame]] was branded upon his chest, and he was sentenced to death. His corpse was to "be hung by his entrails" and "paraded through [[High Charity|the city]]" as an example to others.<ref name="thearbiter">'''Halo 2''', campaign level ''[[The Arbiter]]''</ref>

The Hierarchs, however, had a different fate in mind for Thel. Upon being brought before the High Prophets of Truth and [[Prophet of Mercy|Mercy]], Thel was offered the choice of becoming the new [[Arbiter]]. Understanding that the office of Arbiter was itself a death sentence and seeking to regain his honor, Thel accepted.{{Ref/Reuse|thearbiter}}

{{Quote|What would you have your Arbiter do?|'Vadamee to the Prophets{{Ref/Reuse|thearbiter}}}}

'Vadamee's first assignment as the Arbiter was to stop the [[List of known Covenant heretics|heretic]] uprising based on a [[Threshold gas mine|Forerunner gas mine]] in the atmosphere of [[Threshold]]. He was assisted by [[Rtas 'Vadumee]], [[Special Operations Sangheili]] and [[Special Operations Unggoy]].{{Ref/Reuse|thearbiter}} The operation was complicated by the unexpected escape of the Flood from the facility. During the chaos that followed, the Heretic leader [[Sesa 'Refumee]] sealed himself in a protected zone of the station. The Arbiter drove the Heretics out by cutting the cables from which the facility hung, causing the gas mine to fall. After crashing his [[Type-26 Banshee|Type-26AZ Banshee]], the Arbiter fought his way through the Flood and surviving Heretics toward the station's hangar. Before Sesa 'Refumee could escape in a [[Type-31 Seraph]], the Arbiter assassinated him, but not before the Heretic Leader revealed the source of his heresy. The Arbiter was surprised to discover that the Heretics had been aided by a Holy Oracle, the [[Monitor]] [[343 Guilty Spark]].<ref name="

With the uprising suppressed, the [[Jiralhanae]] [[Chieftain of the Jiralhanae|Chieftain]] [[Tartarus]] extracted the Arbiter and used the [[Fist of Rukt]] to capture the Oracle. His actions, which involved throwing the Oracle into the {{Pattern|Kez'katu|Phantom}} recklessly, angered the Arbiter's religious sensibilities. With Tartarus, he left the gas mine via Phantom, as ''[[High Charity]]'' and the fleet departed the Threshold system.{{Ref/Reuse|theoracle}}

[[File:H2A-Arbiter&Prophets.jpg|thumb|250px|Thel 'Vadamee with Prophets of Truth and Mercy.]]

Aboard ''High Charity'', Arbiter Thel 'Vadamee witnessed the [[Changing of the Guard|replacement]] of the [[Sangheili Honor Guardsman|Sangheili Honor Guardsmen]] with the [[Jiralhanae Honor Guardsman|Jiralhanae]] as a result of Regret's assassination at the hands of the human [[Demon]]. Though distressed by change, and voicing his concerns to the Prophet of Truth, 'Vadamee made no further comment, as he has found out that the Covenant found another [[Installation 05|Halo]]. The High Prophets, who were surprised by both the fact that 'Vadamee had escaped from the Threshold gas mine and that he helped recover the Monitor Guilty Spark (the "Holy Oracle" to whom they inquired about Halo), decided to send him to Installation 05's "[[Quarantine Zone]]" to retrieve the [[Activation Index|"Sacred Icon"]]. This holy relic was needed to activate Delta Halo and begin the Great Journey. On the way to the surface via a Phantom captained by Tartarus, Thel learned from Jiralhanae Chieftain that it was the [[John-117|Demon]], the very same one responsible for Installation 04's destruction, who assassinated Regret.

Thel made his way through the [[Sentinel Wall]] (with a few surviving [[Unggoy]] and [[Kig-Yar]]) to deactivate the [[Library]]'s [[quarantine shield]], fighting a number of Sentinels and Enforcers, eventually passing by dead Jiralhanae on the way. He eventually deactivated the shield, but before Tartarus could pick him up, an Enforcer fired on his Phantom forcing him to break off. The situation was soon complicated when it was discovered that the Flood was running loose throughout the Wall and fighting the Sentinels. He progressively made his way on foot, briefly bearing witness to Human Marines being overrun by the Flood, who were slowly overwhelming the facility. Eventually, Thel made it to the other side of the Sentinel Wall, just as a [[Sentinel manufacturing facility]] was shot down by a Wraith mortar. Just as the Arbiter engaged the Flood on the ground, several [[Udka-pattern Assault Carapace|drop pods]] landed with [[Special Operations Sangheili]] aiding him in his rendezvous with a very surprised Rtas 'Vadumee, who commanded the Sangheili to hold off the Flood until Phantoms could drop in reinforcements, and after a tough fight, they did.<ref name="sacredicon">'''Halo 2''', campaign level ''[[Sacred Icon]]''</ref>

[[File:H2A - Rtas rallying troops.jpg|thumb|250px|left|Rtas 'Vadumee rallies his Sangheili to battle.]]

It was then when the Arbiter filled the Spec Ops Commander on the former's mission to find Halo's Sacred Icon. Rtas pledged his help and ordered his troops to accompany Thel, but not without warning him to not underestimate the Flood. The Arbiter then made his way through various structures and canyons where Sentinels and Enforcers were fighting Flood who commandeered numerous vehicles such as Ghosts, Wraiths, Warthogs, Specters, and even a Scorpion, before traversing through the same Sentinel Manufacturing facility he saw get shot down earlier. Eventually, Thel and Rtas found a Gondola that would take them straight to the Halo's Library, where the former's objective was located. However, they discovered that humans have commandeered another gondola and are heading for the same destination. But with incoming Flood approaching from behind, the Spec Ops Commander stays behind and holds them off while the Arbiter takes the Gondola ahead with remaining Sangheili reinforcements. Wave after wave, the Flood attacked, but the Arbiter and his allies managed hold them off until the Gondola reached its final destination.

 

The Arbiter proceeded into the Library, encountering the remains of a battle between [[UNSC Marine Corps|UNSC Marines]], [[Sentinel]]s and [[Flood combat form]]s, and witnessed [[Miranda Keyes|Commander Miranda Keyes]] and [[Avery Johnson|Sergeant Johnson]] retrieving the Index. Using his armor's active camouflage, he stalked Johnson and Keyes. Leaping out of the shadows, 'Vadamee surprised Johnson, knocking him unconscious after a brief tussle. Keyes attempted to shoot Thel, but was quickly overpowered and disarmed. Tartarus then arrived and captured Keyes by using his hammer's gravity manipulation abilities, claiming the Index for himself. Tartarus informed Thel about the Jiralhanae's [[Great Schism|intended genocide]] of the increasingly "incompetent" Sangheili. Thel angrily proclaimed that the High Prophets would kill him for this treachery, only to be horrified that this treachery was sanctioned by the High Prophets themselves. The Chieftain then knocked the stunned Arbiter into a pit leading to the depths of Installation 05.{{Ref/Reuse|quarantinezone}}

{{Quote|Tartarus, the Prophets have betrayed us.|Thel 'Vadamee's last attempt to convince Tartarus of the truth{{Ref/Reuse|TGJ}}}}

The Arbiter was rescued from his fall by the [[Gravemind]], the central intelligence of the Flood, and brought to its lair. It was here that the Arbiter met [[John-117]] for the first time. Bringing forth the assimilated [[Prophet of Regret]] and [[2401 Penitent Tangent]], the Gravemind attempted to convince 'Vadamee that the Halos were weapons of destruction, not a path to transcendence, a position which John supported. However, the Arbiter was resistant, though his attention was drawn when the Gravemind mentioned the possibility of everything perishing "as they did before." In order to "show the truth" to the resistant Arbiter, the Gravemind [[teleportation grid|teleported]] him to one of two likely spots it believed the [[Activation Index|key]] needed to stop the Halo's firing would be located.<ref name="Gravemind">'''Halo 2''', campaign level ''[[Gravemind (level)|Gravemind]]''</ref>

 

The Arbiter was teleported to the vicinity of Delta Halo's Control Room. Observing firsthand the results of the Prophets' betrayal, the Arbiter joined forces with a band of Special Operations Commandos and quickly became a leader in the [[Covenant separatists|separatist]] movement. This small unit wasted little time in massacring the Jiralhanae responsible for executing the [[Sangheili Councilor]]s.<ref name="Uprising">'''Halo 2''', campaign level ''[[Uprising]]''</ref> Eventually, Thel met Rtas 'Vadumee, joining forces to reach a {{Pattern|Protos|Scarab}}. Near the Scarab, the Arbiter managed to rescue several separatist prisoners, as well as a group of UNSC Marines including Sergeant Avery Johnson. Johnson negotiated a tenuous alliance with the Arbiter in order to prevent Tartarus from activating Installation 05. Given the extreme danger posed by the ring, they both agreed that Tartarus had to be stopped at all costs. Johnson led the offensive, using a captured Scarab to eliminate ground units while Thel provided air support with a Type-26A Banshee. Together, they punched a hole through Covenant lines and reached the Control Room of Installation 05.<ref name="TGJ">'''Halo 2''', campaign level ''[[The Great Journey]]''</ref>

 

With this revelation, which confirmed everything that the Gravemind and [[John-117]] had tried to tell him, the Arbiter lost any remaining faith in the Great Journey and attempted to convince Tartarus to see reason. The Chieftain however, remained loyal to the Prophets. In the battle that followed, the Installation was activated. With the firing process enabled, the Arbiter, with sniper support from [[Avery Junior Johnson|Johnson]], killed Tartarus after a prolonged firefight. Miranda Keyes then rushed to remove the Index, preventing the activation of the array.{{Ref/Reuse|TGJ}}

The shutdown, however, activated a failsafe system; the rest of the Halos were set to standby mode, and could only be activated remotely from what Spark informed them was [[Installation 00|"The Ark"]]. After the Arbiter asked him its location, Spark gave them coordinates to [[Earth]].{{Ref/Reuse|TGJ}}<ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 197''</ref>

The release of the Flood from the ring, however, would put their plans to get to Earth on hold: the Arbiter would once again rendezvous with 'Vadumee, now shipmaster of the recently-captured [[assault carrier]] ''[[Shadow of Intent]]'', flagship of the separatists' fledgling [[Fleet of Retribution]].<ref name="universe">[https://www.halowaypoint.com/en-us/universe/vehicles/shadow-of-intent '''Halo Waypoint''': ''Shadow of Intent'']</ref> Together, they formulated a plan for sterilization and quarantine. Spark remained with the fleet to coordinate containment efforts while the Arbiter, Keyes and Johnson raced back to Earth aboard one of the fleet's vessels to warn humanity and to locate the Ark.{{Ref/Reuse|LongRoad}}<ref name="lootcrate2">'''[[Halo Legendary Crate]]''', ''[[Halo Legendary Crate/Data Drops|Data Drop #2]]''</ref>  

Like many Sangheili after the Great Schism, 'Vadamee abridged his surname to "'Vadam", symbolizing his resignation from the Covenant.<ref>'''Halo Encyclopedia: The Definitive Guide to the Halo Universe''', ''page 126''</ref>

[[File:Master Chief & The Arbiter.jpg|thumb|250px|Master Chief and Thel 'Vadam in the jungles of Kenya, Africa.]]

'Vadam, Johnson, and Keyes arrived at [[Earth]] on or before November 15, 2552,{{Ref/Reuse|lootcrate2}} taking up residence in the [[Crow's Nest (location)|Crow's Nest]] base near the [[Portal at Voi|supposed Ark]]. After Truth's arrival two days later, and Chief's subsequent bailout from his command ship, 'Vadam, Johnson and several of his allies discovered the Master Chief's point of impact in [[Tanzania]]. When John regained consciousness, he attempted to kill 'Vadam with Johnson's [[M6G Personal Defense Weapon System|sidearm]]. Johnson quickly informed the Spartan that the surviving Sangheili had allied with humanity after the Chief's last encounter with them. The Chief took Johnson's word, and 'Vadam assisted the Master Chief through the jungles near [[Mount Kilimanjaro]], guiding him through the dense forest to the [[A2 Hydroelectric Facility|dam site]].<ref name="Sierra117">'''Halo 3''', campaign level ''[[Sierra 117]]''</ref> He then aided the Chief and the other UNSC forces during the defense of Crow's Nest from Truth's forces.<ref name="CrowsNest">'''Halo 3''', campaign level ''[[Crow's Nest]]''</ref>

Thel rejoined John-117 at the docks, shortly after the Master Chief cleared the road to Voi of Covenant by destroying a Scarab. The two then attacked a section of the Covenant mechanized presence defending the area around the [[Portal at Voi|Forerunner Portal]], which took them through a Traxus warehouse and in a confrontation with a pair of [[Mgalekgolo]] who sided with Brutes. Along the way, he cursed at a preaching hologram of Truth and declared that he will never again be [[Mark of Shame|shamed]], cementing his newfound hatred toward the last surviving Hierarch of the Covenant, and still fuming over his betrayal and lies.

 

Opening a hole in the Covenant anti-air defenses, [[Terrence Hood|Lord Hood]]'s remaining ships assaulted the Prophet of Truth's [[Anodyne Spirit|Forerunner Dreadnought]]. The airstrike was insufficient to destroy the ancient Keyship, and the activated artifact formed an enormous [[slipspace portal]] through which Truth and the Covenant fleet retreated. Before Lord Hood could consolidate the scattered human resistance, a [[Indulgence of Conviction|Flood-infested Covenant cruiser]] transitioned out of Slipspace and crashed into the city, infesting a significant area in and around Voi.<ref name="TheStorm">'''Halo 3''', campaign level ''[[The Storm]]''</ref>

 

 

 

Conferring aboard the Sangheili flagship ''[[Shadow of Intent]]'', the allies learned from a message sent by the AI Cortana (which was repaired by 343 Guilty Spark), that the Flood were on their way to Earth. However, she claimed that the Gravemind was unaware of the Portal at Voi, and that there was a solution to the Flood on the other side; one that would eliminate the parasite once and for all without the need to fire the entire Halo Array. After the message's conclusion, the Sangheili chose to follow the Covenant fleet and deal with the Brutes and Truth. Tensions quickly rose with Lord Hood wishing to make the UNSC's stand on Earth, and Rtas gravely claiming that Earth would not survive the Flood. Thel supporting John's desire to pursue Truth and attack the Flood preemptively, claiming that if Cortana was wrong, then there would be no way to stop the Flood. After the decision was reached, the Sangheili allowed at least two UNSC frigates, including the ''[[Forward Unto Dawn]]'', to accompany them through the portal and find Cortana's solution to the Flood.{{Ref/Reuse|Floodgate}}

Arriving at the Ark, the Arbiter joined the Master Chief at the entrance of a local [[Cartographer]] facility to clear their way, shortly after the Sangheili annihilated Truth's Covenant fleet. Once there, they learned of Truth's location, as well as the forces he had deployed to the Ark's surface. When the group was attacked, the Arbiter joined the battle for air superiority, instructing John to follow 343 Guilty Spark to a nearby location for extraction.<ref name="TheArk">'''Halo 3''', campaign level ''[[The Ark (level)|The Ark]]''</ref>

With the destruction of the Covenant fleet, Rtas 'Vadum's carrier positioned itself near the Ark's [[Installation 00 Citadel|Citadel]] - where Truth planned to remotely activate the rings. Commander Keyes led a three-pronged assault on the shield generators protecting Truth's citadel, with the Arbiter leading a Sangheili squad to deactivate the second tower, while the Chief would handle and first and Johnson the third. While both John and Thel succeeded in deactivating their towers, Sergeant Major Johnson failed to deactivate the third generator due to heavy Jiralhanae resistance. After the Chief made his way to the third tower, the Arbiter landed his forces at the third tower to support the Master Chief in successfully deactivating the final generator and shutting down the barrier, pushing through packs of Jiralhanae, a swarm of Yanme'e, and a pair of Mgalekgolo along the way.{{Ref/Reuse|TheCovenant}}

With the barrier disabled, Shipmaster 'Vadum prepared to bomb Truth's position, but ''High Charity'' suddenly exited Slipspace and crashed into the Ark. In its plummet to the surface, ''High Charity'' scattered a barrage of infection capsules which crippled the carrier. The Arbiter led his forces in conjunction with the Marines to clear the third tower of Flood, with the Chief's assistance. As a security measure, the Arbiter escorted a distressed 343 Guilty Spark to reconnoiter the damage inflicted to the Ark by the Flood, leaving his Sangheili with the Chief to push on to the Citadel.{{Ref/Reuse|TheCovenant}}

With the Covenant, including two Scarabs, guarding the Citadel defeated, Thel and John entered the Citadel, with the latter making clear that the Prophet of Truth would die by the Arbiter's blade, not the Flood who were scaling the Citadel's walls. They saw Truth broadcast his "faithful" and intending to activate the Halo Array with Johnson as a captive. As the Spartan and the Arbiter reach the top of the elevator shaft leading to the Citadel's control room, the Flood [[Gravemind]] unexpectedly formed a tentative alliance with them, claiming that it would cooperate with them in order to kill Truth and abort the firing of the [[Halo Array]]. Fighting through the remains of Truth's forces, this unlikely alliance eventually approached the location of the last High Prophet of the Covenant, briefly mourning the death of Miranda Keyes.

 

The Arbiter furiously approached Truth, who had been infected by the Flood and was slowly undergoing mutation, and declared his dogmatic claims about the Great Journey would not last. The Gravemind spoke through Truth, informing Truth that he was deluded to think he could achieve godhood, and claimed he would be "food, nothing more". It was then that Thel declared that he would have his vengeance upon a Prophet, not a disease, but not before forcing Truth to see John deactivate the Halo Array, with Truth expressed one final defiance as the "voice of the Covenant". With little hesitation, Thel "silenced" Truth, by impaling him with his energy sword before his Flood transformation could progress. At that moment, the leader of the Covenant fell dead with John looking on, but they were suddenly faced with the betrayal of the Flood, which now no longer faced any obstacles in killing the two and going on to consume the galaxy.{{Ref/Reuse|TheCovenant}}

{{Main|Raid on High Charity|Raid on Installation 08}}

The two then escaped on a [[D77H-TCI Pelican]] as High Charity exploded behind them. The Pelican flew past the ''Shadow of Intent'', which has successfully evacuated all surviving Humans and Sangheili from the Ark, with the Thel declaring to Rtas that he will see the fight against the Flood be finished and decided to accompany his newly-befriended Spartan ally as their Pelican crashed onto the snowy cliffs of Installation 08. Scaling through the icy caverns, the pair approached an exact replica of the original Halo's control room as multiple [[Flood dispersal pods]] rained down around them and poured countless combat forms and pure forms around them. Aided by the Halo's sentinels, and eventually Johnson armed with a Spartan Laser, the Chief and the Arbiter made their way up the ziggurat fighting numerous Flood forms floor by floor. As they reached the top, the enraged Gravemind made one last defiant effort to kill the two soldiers, dropping countless forms to swarm and kill them, but they were unsuccessful as they rendezvoused with Sergeant Major Johnson and entered the structure as more dispersal pods were landing outside. Once the trio approached the control room, Thel stayed to cover the door as they heard a multitude of Flood closing in from behind.  

[[File:Halo Chief Arbiter.jpg|thumb|left|250px|John-117 and Thel 'Vadam in Johnson's Warthog.]]

343 Guilty Spark suddenly appeared in the control room, but the Monitor betrayed them after realizing that an immediate activation of the incomplete ring would destroy it and damage the Ark. In the battle that followed, the [[rampancy|rampant]] 343 killed Johnson and knocked the Arbiter out of the room. After the destruction of 343, and a solemn Cortana's activation of Halo via the Index, Thel expressed sorrow over Johnson's death, noting his sacrifice would not be forgotten. Making their way outside, with Halo shaking and exploding all around them, they fought more Flood and the now-hostile Sentinels, and backtracked the path Johnson took along the canyons walls in order to escape on the ''Forward Unto Dawn''. Once John, Thel, and Cortana travelled through a pulse generator, they found a [[Warthog]] left behind by Johnson, and resolved to escape the crumbling Halo. It was a long drive through skirmishes of Flood and Sentinels and falling debris all around, but the trio succeeded in reaching the ''Forward Unto Dawn'' and escaped the Ark and Halo just before it fired. Before departing to the bridge, Thel and John nodded to each other, a moment of mutual respect between warriors. This would be the last time 'Vadam would see the Chief for several years, as he then exited the hangar, and made his way to the bridge, while Chief and Cortana stayed behind and guided the frigate to its jump point, but the slipspace portal collapsed as ''Forward Unto Dawn'' transitioned.  

The aft end of the ship, with John-117 and Cortana aboard, was sheared off and left adrift in unknown space. The bow section, containing 'Vadam, completed the jump and crash-landed on Earth, where he was rescued. The Covenant Empire had ceased to exist, and Thel began the first steps to bring his people into a new future.{{Ref/Reuse|Halo}}{{clear}}

[[File:H3 Arbiter CommandChair.png|250px|thumb|Fleetmaster Rtas 'Vadum (background), passes leadership of their people over to Arbiter Thel 'Vadam, giving him the chair.]]

Thel acted as a voice of reform to the Sangheili, uniting the keeps under a new planetary government, the [[Swords of Sanghelios]]. Returning to his [[Sanghelios|homeworld]], he planned to visit each state to make his case for permanent peace with the [[human]]s they had battled for so many years;<ref>'''[[Halo: Glasslands]]''', Chapter 5, ''page 130''</ref> one of these would be a meeting in the state of [[Mdama]]. It was here that he announced that he no longer felt he was an Arbiter, but simply a [[Kaidon]]. He told the elders that if any of them disagreed with him strongly enough, they could attempt an assassination as per Sangheili tradition.<ref>'''Halo: Glasslands''', Chapter 2, ''pages 58-61''</ref>

These reforms did not meet with universal approval. By January 2553, there was great dissent among disparate Sangheili parties, especially from the more devout believers in the Forerunners' divinity. Some, such as [[Avu Med 'Telcam]] and his [[Servants of the Abiding Truth]], saw the Arbiter as a [[Treason|false]] leader that has betrayed their pre-Covenant worship of the [[Forerunner]]s and sought to preemptively strike at humanity, fearing they would retaliate for the war. Additionally, many devout believers regarded Thel a "false Arbiter", stating that his very existence was heretical as he did not sacrifice himself the battle as was traditional of Arbiters in the Covenant. Others opposed 'Vadam not on religious grounds but due to his alliance with humanity, considering the notion of peace with the humans hopeless and that they could not be trusted.{{Ref/Reuse|wp thel}} Thel argued with logic, they had not only failed to defeat humanity in the end, but attacking them would bring Sanghelios to ruin after the sundering of the Covenant had left their people without the technical expertise to replace lost warships, or maintain their own infrastructure.

On March 3, 2553, 'Vadam was present at the dedication of the memorial to those humans lost during the Covenant War. He was thanked by Hood for standing alongside John-117 "to the end"; knowing the resilience of the Spartan first hand, Thel expressed doubt as to the soldier's death. The Arbiter departed for Sanghelios aboard the ''Shadow of Intent'' along with Rtas 'Vadum, to ensure the security of their people.{{Ref/Reuse|Halo}}

[[File:HM-Thel.png|thumb|250px|Thel 'Vadam, outfitted in his new armor, during the Blooding Years.]]

Later in 2553, 'Vadam sent 'Vadum on missions to the frontier colonies to give the shipmaster a much needed break from combat. However, during these missions, 'Vadum encountered a surviving Covenant [[Prelate]] and [[Minister (title)|minister]]—[[Tem'Bhetek]] and [[Boru'a'Neem]] who led [[Jiralhanae]] forces. With the help of [[Tul 'Juran]] of [[Rahnelo]], 'Vadum was able to defeat the two San'Shyuum and their forces. Afterwards, 'Vadum contacted 'Vadam and briefed him on the events that transpired. 'Vadam attempted to convince his friend to return to Sanghelios for a break, but 'Vadum wished to continue his missions in the frontier to search for the remaining San'Shyuum, to which the Arbiter agreed to. At 'Vadum's suggestion, 'Vadam also amended the Swords of Sanghelios' protocol to allow the enlistment of females in the military after 'Vadum personally witnessed the skill 'Juran showed in combat.<ref>'''[[Halo: Shadow of Intent]]''', ''pages 81-83'' (Google Play edition); '''[[Halo Fractures]]''', Shadow of Intent, ''page 149-150''(paperback)</ref>  

 

In [[2555|March of 2555]], the UNSC contacted 'Vadam after discovering that the Halo Array had been set to fire in three weeks. The countdown had been initiated from the Ark, and the UNSC requested the Swords of Sanghelios' aid in re-activating the [[Portal at Voi|portal]] at [[Voi]] in order to dispatch a team there to disable the activation sequence. As he was preoccupied with the ongoing civil war, 'Vadam sent [[Usze 'Taham]] and [[N'tho 'Sraom]], along with several other Sangheili aboard [[corvette]] ''[[Mayhem]]'' and a [[Huragok]] to aid the humans.<ref>'''[[Halo: Hunters in the Dark]]''', Chapter 3, ''pages 59-66''</ref>

In [[2558]], Thel 'Vadam attempted to enter into peace negotiations with the Jiralhanae, with the UNSC ''Infinity'' being assigned to escort him. On March 5, 'Vadam met with Lord Hood and the [[Jiralhanae Chieftain]] [[Lydus]] on [[Ealen IV]]. During the negotiations, [[Vata 'Gajat's mercenary group|Covenant mercenaries]] led by [[Vata 'Gajat|Shipmaster 'Gajat]] attacked the delegates. [[Captain (Navy)|Captain]] [[Thomas Lasky]], [[Sarah Palmer|Commander Sarah Palmer]], and the [[SPARTAN-IV Program|Spartan-IVs]] defended the delegation and evacuated them from the chamber. Lydus accused 'Vadam of betraying him, but Thel reassured him that he had no part in the attack as he killed a [[Kig-Yar Sniper]] attempting to assassinate Lydus. When their evacuation ship was destroyed, the security detail proceeded to escort the delegates to a nearby parts depot.<ref name="Esc1">'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 1|Issue #1]]''</ref>

Inside the repair depot, 'Vadam notified Hood and the rest of an old fortified redoubt in which they could take refuge in. Captain Lasky ordered Palmer and the protection detail to escort the delegation to the redoubt. As the party escaped the depot, they were intercepted by a Covenant [[Kmiro'sish-pattern Lich|Lich]]. Palmer quickly acted and threw her helmet filled with grenades and destroyed the Lich. The delegation stayed back as [[Fireteam Jackknife]] and their bodyguards went ahead to ensure the redoubt was safe for them to use as shelter.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 2|Issue #2]]''</ref> However, as the delegates entered the redoubt, [[Vladimir Scruggs|Spartan Scruggs]] of [[Fireteam Jackknife]]—who had betrayed his team—ambushed the group and held Hood hostage. 'Vadam queried Scruggs on what his demands were; Scruggs stated that they would discuss them once his associates arrived. With the Covenant bearing on the site in force, the ambassadors' security detail discovered [[Covenant cargo tug|a craft]] they could use to evacuate. Thanks to the sacrifices of Fireteam Bailey, the delegation, Lasky and the surviving Spartans made it aboard ''Infinity'', which rallied the feuding Sangheili and Jiralhanae fleets and forced 'Gajat's forces into retreat.<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 3|Issue #3]]''</ref>

Following [[Jul 'Mdama]]'s death on [[Kamchatka]] in [[2558#October|October 2558]], the remaining forces of [[Jul 'Mdama's Covenant|'Mdama's Covenant]] regrouped and launched an assault on Sanghelios.<ref name="sos">'''Halo 5: Guardians''', campaign level ''[[Swords of Sanghelios (level)|Swords of Sanghelios]]''</ref> 'Mdama's Covenant used the city of [[Sunaion]] over [[Csurdon Sea]] as a staging point to launch an attack against Swords of Sanghelios territory, though the Arbiter countered this move by establishing a forward operating base in the ruins of [[Nuusra]] on the sea's coast.<ref>[https://www.halowaypoint.com/en-us/universe/locations/sunaion '''Halo Waypoint''': ''Sunaion'']</ref> However, 'Mdama's Covenant attacked first and laid siege to the Swords of Sanghelios base on Nuusra, pushing back 'Vadam and his forces to the [[Elder Council Chamber]].{{Ref/Reuse|sos}}

 

 

Returning to the Arbiter's primary camp in Nuusra with Palmer and Halsey, 'Vadam and Osiris leader Spartan [[Jameson Locke]] spoke about using Sunaion's Guardian to pursue Blue Team, with the latter greeting and thanking the former for his cooperation on behalf of Captain [[Thomas Lasky|Lasky]]. While understanding of Spartan Locke's intentions, he was understandably distrustful of the human standing before him, not only because of the ONI logo on his armor, but he somehow recognized him as the very [former] [[Terminal (Halo 2: Anniversary)/One|agent]] [[Terminal (Halo 2: Anniversary)/Two|who]] [[Terminal (Halo 2: Anniversary)/Three|volunteered to terminate]] him during the [[Human-Covenant War|war]]. In response, Locke sternly-yet-politely pointed out that he saved his life. And 'Vadam was even more concerned that he was hunting the very Spartan he fought alongside with six years ago, whom he referred to as the "greatest of [the Spartans'] clan". However, using her recently gained access to the [[Domain]], Cortana suddenly blacked out every network at the camp, taunting Locke in the process. Halsey came up with a plan that involved locating a Forerunner [[Constructor]] at a support station for the Guardian and inputting commands into it to make the construct activate the Guardian for Osiris. And while the Swords of Sanghelios had the firepower to get the Spartan-IVs in Sunaion, he refused to commit to an attack on the final stronghold of Jul 'Mdama's Covenant until victory was a guaranteed certainty. He was briefing his fellow Swords at the camp who were alarmed by Cortana's disruption, reminding them they fight one enemy at a time; their target being 'Mdama's Covenant. While his Sangheili were alarmed by the Guardian's inevitable reawakening, he assured them that he was relying on it, stating that the Guardian's departure in the eyes of 'Mdama's Covenant who worship it and its makers will be further demoralized upon seeing their idol deity depart and abandon them to their fate at the hands of the Swords. '<ref name="alliance">'''Halo 5: Guardians''', campaign level ''[[Alliance]]''</ref> At some point, from his security officer Mahlo 'Turagg (via an interrogation toward a Covenant Unggoy), Thel discovered that [[Murok 'Vadam]], one of his own family, was the one who betrayed him and left him to die during 'Mdama's Covenant's attack at the Elder Council Chamber. Murok was cooperative during his interrogation, thinking the Arbiter wouldn't kill anyone from his own clan; he was soon proven wrong as Thel executed him for his treachery.

Jul 'Mdama's Covenant deployed a {{Pattern|Shuul'se|Kraken}} between the support station and Osiris' position. While the Arbiter's forces engaged the Kraken with air squadrons, Osiris provided ground support. While the Swords of Sanghelios pushed the Kraken into a retreat, Osiris boarded the walker and destroyed its power core. With the Kraken destroyed, Osiris entered the nearby Forerunner support station and retrieved the Constructor. However, the Spartans were suddenly engaged by [[Promethean]] constructs.<ref name="enemy lines">'''Halo 5: Guardians''', campaign level ''[[Enemy Lines]]''</ref> After battling their way to the extraction point, Osiris returned to the Swords of Sanghelios camp at Nuusra, where 'Vadam and Spartan Palmer were discussing the aerial assault on Sunaion, and was ready to begin his attack and finally destroy 'Mdama's Covenant. As the Constructor departed to activate the Guardian, the Arbiter's forces launched their assault on Sunaion.<ref name="before the storm">'''Halo 5: Guardians''', campaign level ''[[Before the Storm]]''</ref>

 

===Meeting an old friend===

[[File:ArbiterAndChiefReunion.png|250px|thumb|Arbiter Thel 'Vadam reunites with his Spartan friend, John-117, for the first time in years.]]

After his victory at Sunaion, 'Vadam and his forces returned to their campsite at Nuusra with Halsey and Palmer. However, during this time, a Guardian returned back to Sanghelios after the Sangheili refused to surrender to the [[Created]], a faction of rogue artificial intelligences founded by Cortana. The Guardian finished off the remaining Covenant ships and began blacking out the planet with ground assistance of Prometheans which were sent in to pacify cities that refused to surrender.{{Ref/Reuse|BB}}

 

 

In late [[2559]], three days after Cortana had [[Razing of Oth Sonin|destroyed]] the Jiralhanae homeworld of [[Doisac]], Thel 'Vadam [[High Gathering|met]] with the [[Kaidon|high kaidons]] of several [[Sangheili colonies]]. At this meeting, 'Vadam proposed the [[Concert of Worlds]], intending to unify the Sangheili and take their fate into their own hands rather than submit to the tyranny of Cortana. No agreements between any of the officials could be made at the meeting, and 'Vadam left the gathering frustrated by the lack of progress. The Arbiter and his escorts—Usze 'Taham and [[Kola 'Baoth]]—returned to Vadam keep in a [[Crav]] operated by his adjunct, N'tho 'Sraom. As they passed through the [[Old Borough]] in [[Vadam Valley]], the Crav was stopped by Created [[armiger]]s who were looking for participants of a recent fight at the tenement islands by the [[Kolaar Manufactorum]]. Although his associates were reluctant, 'Vadam consented to a search of the Crav. During the search, the group's weapons were confiscated, to the outrage of 'Vadam's escorts. Understanding that striking down the armigers would result in a chain of events ending with the appearance of a Guardian, 'Vadam had his men back down.{{Ref/Novel|Id=Out1|Out|Chapter=1}}

After he returned to his keep, 'Vadam was informed that [[Crei 'Ayomuu]], an [[Oath Warden]], had arrived to speak with him. From this Sangheili, 'Vadam learned of the true events at the tenement islands: armigers had ransacked the settlement in search of a human [[Xenoarchaeology|xenoarchaeologist]] named [[Keely Iyuska]] who had discovered that the planet [[Netherop]] might hold the key to defeating the Created's Guardians. Still suspicious of 'Ayomuu and his client, Thel 'Vadam agreed to assist the Oath Warden in his search for Iyuska, whom he had be contracted to locate.{{Ref/Novel|Id=Out2|Out|Chapter=2}}

Later on, Thel 'Vadam and [[Spartan-IV]] [[Olympia Vale]], led a mission on the hostile world of Netherop in an attempt to locate a rumored ancient artifact which could be the key to ending the Created's rule over the [[Milky Way|galaxy]].{{Ref/Novel|Id=OutSummary|Out|Detail=Official summary}}

Thel, like most Sangheili, held an obsession with honor and tradition for most of his adult life. However, he was more flexible than his peers when it came to the tactics that he used, and in particular showed a keen interest in human weapons even before the Great Schism. His worldview changed greatly during the Great Schism. While once zealous and unquestioningly obedient to the Prophets' will, after learning of the true nature of the Halo rings, he became more open-minded and accepting of the humans, his former enemies. His experiences as Arbiter also made him more pragmatic than most Sangheili, being willing to accept help from the UNSC in fending off an assault on [[Vadam keep|his keep]]. He has shown to be true to his title "Arbiter", and sometimes tries to negotiate with his enemies, such as [[Yanme'e]] during the Battle for Earth (though this fell on deaf ears).

As noted by [[Jameson Locke]] in his [[target profile]] on him, Thel was an incredibly brilliant commander, known for utilizing advanced tactics that made his fleet unstoppable. Among the Covenant, he was noted for being one of the youngest Sangheili to attain the ranks of both Shipmaster and Supreme Commander.<ref name="a2at12">'''Halo 2: Anniversary''', ''[[Terminal (Halo 2: Anniversary)|Terminal 12]]''</ref> During the war, 'Vadamee was known for his tendency to lead campaigns from the front lines. His unorthodox tactics in comparison to the Covenant at large quickly caught the eye of ONI; Lieutenant Commander Locke considered him the most dangerous asset the Covenant had due to his strategic unpredictability and tactical flexibility.{{Ref/Reuse|a2at1}} After the [[Fall of Reach]], 'Vadamee's influence within the Covenant fleet had grown so great [[Sesa 'Refumee]] suspected the Prophets may perceive him as a threat to their power even before learning of his appointment as Arbiter.<ref name="a2at13">'''Halo 2: Anniversary''', ''[[Terminal (Halo 2: Anniversary)|Terminal 13]]''</ref>  

Thel also managed to inspire great loyalty in his subordinates. While [[Rtas 'Vadum]] initially lost his respect for Thel for the loss of Installation 04,{{Ref/Reuse|thearbiter}} Thel's subsequent actions at the gas mine and Installation 05 restored it and strengthened their comraderie, to the point where Rtas spared Earth from a full Flood-quelling [[glassing]] at Thel's urging.{{Ref/Reuse|Floodgate}} [[Jora 'Konaree]] thought of him like a cousin, and Sesa 'Refumee considered him to be the only individual that he would trust with [[343 Guilty Spark]]'s revelations, though Thel's appointment as Arbiter prevented any detailed conversations.{{Ref/Reuse|a2at13}} Even so, however, he was able to comprehend the same message when it was told to him by the [[Gravemind]], [[John-117]], and [[343 Guilty Spark]].{{Ref/Reuse|TGJ}}{{Ref/Reuse|Gravemind}}

After the Battle of Installation 04, he was ashamed for his failure at Halo, and wished only to regain his honor before dying for the Prophets. He remained stubbornly attached to his faith even after the betrayal of Tartarus and his encounter with the Gravemind. However, when he heard the truth of the Sacred Rings from 343 Guilty Spark, he finally accepted the truth surrounding the Great Journey. Following his betrayal by the Prophets, Thel developed an intense hatred of both the San'Shyuum and the Jiralhanae. Despite this, Thel was gracious enough to attempt to reason with the Jiralhanae Chieftain [[Tartarus]] in [[Control Room (Installation 05)|Installation 05's Control Room]].{{Ref/Reuse|TGJ}}

Despite his former hatred for humans, Thel has displayed great respect for some, even former battlefield foes. He also holds admiration for humanity's courage; this is most clearly seen by his actions to avoid the glassing of Earth, even though that meant risking a possible Flood outbreak. Presumably due to the role Johnson played in his killing of Tartarus, Thel respected him greatly and grieved his death, expressing sorrow to the Master Chief, but promising that his sacrifice would not be in vain. Despite initially hating the Master Chief greatly for destroying Installation 04 and being the "Demon" of the Covenant who killed so many soldiers, the Arbiter came to greatly respect and trust the Chief. The Chief and Gravemind helped convince him of the truth of the Great Journey and they fought together against the Covenant and Truth. Together they defeated Truth and deactivated the Halo Array. When the Master Chief went to rescue Cortana and activate [[Installation 08]], Thel remained behind to help him and shared a nod of respect with him when it was over. Even though the Master Chief was believed to be dead, Thel showed disbelief in this presumption, confident that the Spartan had survived thanks to his extraordinary ability to overcome impossible odds. After the events of Ealen IV and discovering the Chief was still alive, Thel believed John was the key to the galaxy's future. He also admitted to Spartan Locke that even when they were enemies and he called the Chief "Demon," it was with a modicum of respect for him. He also admitted that after their alliance he came to see the Chief as an ally as well as his friend.<ref name="TargetLocke">'''Halo 2: Anniversary''', campaign level ''[[The Heretic]]''</ref> Before Fireteam Osiris entered the Guardian on Sunaion to find the Master Chief, the Arbiter complimented Locke with a Sangheili proverb, and then asked Locke to send the Chief his greetings. Olympia Vale remarked that she had never heard an Elite address a human in such a way.{{Ref/Reuse|sunaion}} After reuniting with the Chief, Thel warmly greeted him and the two spent part of the night catching up on old times. Before they parted ways again, Thel expressed confidence that together as allies they could defeat this new threat.{{Ref/Reuse|BB}}

 

Over the years following the defeat of the Covenant, Thel's respect for humans in general only grew to the point that he developed a fondness for certain humans and was known to use human gestures that he had witnessed, found useful and adopted. Thel learned to speak English fluently so that he could communicate with his human allies more naturally rather than relying on a [[translation disk]].{{Ref/Novel|Out|7}} After meeting [[Lieutenant Commander]] [[Amalea Petrov]] and hearing of her thirty-three year struggle against [[Nizat 'Kvarosee]] and [[Defenders of the Sanctum|forces]], Thel called Petrov and her people worthy warriors with a resolve worthy of a Spartan and Thel privately mused that while he had originally thought of humans as spinless as ''[[slood]]s'' and treated them as such while slaughtering countless humans, Thel came to understand that their treachery was rooted more in perseverance and cunning than cowardice. After Petrov wagged her finger at him, Thel quickly adapted the gesture for his own use, considering it to be effective and remembering it for future interactions.{{Ref/Novel|Out|Chapter=9}} Thel also adopted other human gestures such as the finger gesture for telling someone to hurry up. In many ways, Thel came to see Spartan [[Olympia Vale]] as being akin to his human hatchling because she had impressed Thel with her diligent study of Sangheili culture and her obvious devotion to keeping the peace between Sangheili and humans. In Thel's daydreams, he could envision a day when they sat across from each other as important leaders, working together to create a civilization united in harmony and prosperity.{{Ref/Novel|Out|24}}

During his military career in the Covenant as Supreme Commander, Thel wore a golden Gheocin-pattern combat harness. After falling in disgrace and be appointed Arbiter he started wearing the [[Arbiter body armor|traditional Arbiter armor]]. While 'Vadamee continued donning the traditional Arbiter armor after the war, he has more recently started wearing a custom-built ceremonial battle armor intended to pay homage to past Arbiters and symbolize his newfound role as a leader of his people. This armor is gold-colored and more baroque than his old Arbiter armor. He favors the [[energy sword]], occasionally wielding his personal sword known as the [[Prophets' Bane]].{{Ref/Reuse|wp thel}} Thel most often uses the {{Pattern|Vostu|carbine}} and {{Pattern|Mosa|carbine}} in ranged combat.<ref name="H3">'''Halo 3'''</ref><ref name="H5G">'''Halo 5: Guardians'''</ref>
