{{Quote|Every member of the Covenant shall walk the path. None will be left behind when our Great Journey begins. That is the Prophets' age-old promise, and it shall be fulfilled!|The Prophet of Regret}}

The '''High Prophet of Regret''', born '''Lod Mron''',{{Ref/Reuse|essential}} was the youngest of the three [[San'Shyuum]] [[Hierarchs|High Prophets]] who led the [[Covenant]] [[High Council]] during the [[Human-Covenant War]]. Rash, ambitious, immature, and naive compared to the other Hierarchs, Regret originally served as [[Ministry of Tranquility|Vice Minister of Tranquility]], where he worked frequently with [[Sangheili]] and had adopted some of their personality traits, such as a preoccupation with honor and personal arms.{{Ref/Novel|Id=TCP|TCP}} In many ways, he can be characterized as a Prophet who thought like an Elite; a rare mindset for his species, and from the [[Prophet of Truth|High Prophet of Truth's]] point of view, a dangerous one. Regret was intelligent and fiercely opposed [[human]]ity through the course of the war.<ref>[http://www.gamedaily.com/articles/galleries/halo-wars-character-profile-professor-anders-and-the-prophet-of-regret/?page=1 Professor versus Prophet].

==Biography==
===Age of Doubt===
During the [[Ages of Doubt|23rd Age of Doubt]], [[2524]] by the UNSC [[Military Calendar]], Lod Mron held the post of Vice Minister of Tranquility. He was unique among the Prophets for his confrontational demeanor, a trait he gained from working with the [[Sangheili]].{{Ref/Novel|CH|Page=155}} He informed the [[Ministry of Fortitude|Minister of Fortitude]], [[Prophet of Truth|Ord Casto]] about the existence of [[Harvest]] and what they believed to be a vast repository of [[Forerunner]] artifacts. Tranquility sent a [[Jiralhanae]] [[Maccabeus' clan|crew]] to search for survivors of [[Minor Transgression|the ship]] that discovered Harvest and, at Fortitude's recommendation, told the Jiralhanae to execute survivors if they were found with stolen artifacts.{{Ref/Novel|CH|Page=156-157}} After conspiring with Fortitude to gain these artifacts for their own use, he helped him by pretending to sympathize with those [[Roll of Celibates|blacklisted from reproducing]] due to inbreeding, which included the [[Prophet of Restraint]]. After pretending to be the father of two children Restraint had unlawfully fathered, Tranquility blackmailed Restraint into stepping down from his position as High Prophet.{{Ref/Novel|CH|Page=265-267}}

Before their coup, the Prophets visited the [[Philologist]] [[Prophet of Mercy|Hod Rumnt]], leader of the [[Asceticism|ascetic priests]] aboard the [[Forerunner Dreadnought]] and keeper of the Oracle, which was actually the long-dormant [[Mendicant Bias]], an ancient [[Artificial intelligence|AI]] that had not spoken to anyone for thousands of years.{{Ref/Novel|CH|Page=271}} When the [[Luminary|Luminaries]] of Harvest were entered into its matrix, the Oracle reactivated and said the symbols had been misinterpreted: the symbol didn't mean "Reclamation", but "Reclaimer", who it called his makers. Fortitude concluded that the these Reclaimers, the planet's aliens, were living Forerunners who had been left behind when the others transcended. Tranquility refused to believe this and accused the Philologist of tampering with the Oracle. As it attempted to launch the Dreadnought from ''[[High Charity]]'' the [[Lekgolo]] worms inside the Dreadnought short-circuited it and stopped Mendicant Bias.{{Ref/Novel|CH|Page=274-276}} Fortitude, Tranquility, and the [[Philologist]] made the decision to disconnect the Oracle from the ship and decided to eradicate humanity before any of the Covenant learned that the most basic premise of their faith was false, and that [[human|"living gods"]] would probably replace the Prophets. As such, their ascension was made, taking the names of Truth, Regret and Mercy.{{Ref/Novel|CH|Page=381}}

===Age of Reclamation===
====Human-Covenant War====
[[File:Prophet of Regret.jpg|300px|thumb|left|The High Prophet of Regret during his early years as a Hierarch.]]
{{Quote|The Journey requires sacrifice! Set the charges. Return to us! Our patience is not infinite!|Regret, speaking via hologram to [[Ripa 'Moramee]]}}
Upon the onset of the Human-Covenant War, Regret formalized the [[Fleet of Glorious Interdiction]]; a Sangheili-led military force under his personal supervision,{{Ref/Book|Id=evg|EVG|Page=10}} and appointed [[Arbiter]] [[Ripa 'Moramee]] as its leader, choosing him for his ruthlessness and undying loyalty.<ref name="Loyalty" /> Obsessed with the Forerunners and the prospect of activating the [[Halo Array]], Regret dispatched 'Moramee on numerous missions throughout Covenant and human space to find the means to do this.<ref>[http://www.gamedaily.com/articles/galleries/halo-wars-character-profile-professor-anders-and-the-prophet-of-regret/?page=2 Obsessed Prophet]. ''Game Daily''. Accessed on 2009-01-26</ref> 

At [[Trove]], in a Forerunner installation known as the [[Apex Site]], Regret discussed with Ripa the state of the installation, and that the recently glassed human world [[Harvest]] had a Forerunner [[Relic (location)|relic]] buried in the planet's northern polar region. Regret sent Ripa to go and recover the secrets the site held to hopefully get his key to the Apex Site.<ref name="OSG">''[[Halo Wars: Official Strategy Guide]]'', page 50</ref> However, the relic on Harvest proved to be some sort of Forerunner mapping device, and with [[UNSC]] forces closing in however, Regret ordered that the relic be destroyed to prevent the retrieved information from falling into human hands. Against his instincts, the Arbiter obeyed.{{Ref/Level|HW|[[Relic Approach]]}} However, despite Covenant efforts, the site was not destroyed, allowing the humans to learn of the information that Regret planned to use.

[[File:Vlcsnap-126482.png|250px|thumb|Regret and Ripa 'Moramee.]]
Later, at the Apex Site, Regret discussed with the Arbiter his plans to activate the [[Forerunner]] {{Class|Sojourner|dreadnought}}s located there. When he could not activate the artifact himself, he ordered the Arbiter to capture the human female, [[Ellen Anders]], who they encountered at the "[[Relic (location)|Ice Relic]]" and bring her to the Apex.{{Ref/Level|HW|[[Scarab (level)|Scarab]]}} Later when the Arbiter returned with her, Regret was in disbelief, saying "you would hardly think them a threat." When they learned the humans were closing in on them Regret evacuated to ''[[High Charity]]''.{{Ref/Level|HW|[[Shield World (level)|Shield World]]}} However, Regret's plans to use the dormant ships were foiled when the crew of the {{UNSCShip|Spirit of Fire}} induced the collapse of the Shield World's internal sun, destroying all the ships and the planet. The Arbiter was also killed by Sergeant [[John Forge]] during the battle, depriving Regret of his prized warrior.{{Ref/Level|HW|[[Escape (Halo Wars level)|Escape]]}}

====Rubble crisis====
About four years later, Regret was present at the [[Battle of Charybdis IX]], with his personal [[Covenant cruiser|cruiser]], ''[[Infinite Sacrifice]]'', where he oversaw [[Thel 'Vadam]]ee and his crew destroy three human [[UNSC destroyer|destroyers]]. At Regret's orders, 'Vadamee went aboard the cruiser to report to the High Prophet.{{Ref/Novel|TCP|Page=143}} Aboard the ''Infinite Sacrifice'', Regret showed 'Vadamee a human-modified [[Okarda'phaa-pattern plasma rifle|Covenant weapon]]. Regret revealed that he had found the modified weapons in [[Kig-Yar]] [[black market]]s found on ''High Charity''. Regret told 'Vadamee to find the source of the modified weapons at the [[23 Librae]] system, with a [[Kig-Yar]] [[A Psalm Every Day|vessel]] escort, and execute the Kig-Yar "[[piracy|pirates]]".{{Ref/Novel|TCP|Page=144-146}} As 'Vadamee made his way to return to his destroyer, Regret ordered him to glass [[Charybdis IX]] with the ''Infinite Sacrifice''.{{Ref/Novel|TCP|Page=148}} Little did Regret know that he was, in fact, interfering with the [[Prophet of Truth]]'s plans to find the location of all of the [[human colonies]] and [[Earth]].{{Ref/Novel|TCP|Page=236}}

Several days later, Regret was still in the [[Charybdis system]] when the Prophet of Truth visited his cruiser. Truth revealed his plan to Regret and informed him that the Kig-Yar leader, [[Reth]], was attempting to find the coordinates to Earth while creating a large [[Unggoy]] army. Truth informed Regret that the Jiralhanae crew aboard ''A Psalm Every Day'' had betrayed 'Vadamee and suggested that Regret should execute them to prevent the rest of ''High Charity'' finding out. Then, the ''Infinite Sacrifice'' left the system to follow the coordinates to [[Metisette|the world]] where Reth was creating the Unggoy army.{{Ref/Novel|TCP|Page=285-289}}

After the cruiser arrived in the 23 Librae system, the Hierarchs discovered that the human [[Insurrectionist|insurgent]] base, [[the Rubble]], had been destroyed in [[Battle of Metisette|a battle]], and unfortunately Reth and his army were killed. After the battle, 'Vadamee and [[Zhar (Sangheili)|Zhar]] were brought before Truth and Regret aboard the ''Infinite Sacrifice''.{{Ref/Novel|TCP|Page=340}} Upon being told that he was to be executed for his failures, Zhar drew his [[Type-1 energy sword|energy sword]] with the intent to murder the Prophet of Truth. However, Thel anticipated Zhar's attack, decapitating his former friend with his own energy sword. This left Regret heavily shaken. In return, 'Vadamee was granted command of a ship in a [[Fleet of Particular Justice|new Covenant fleet]] and was ordered never to speak of the events that had transpired.{{Ref/Novel|TCP|Page=341}} After the incident, the two Hierarchs returned to ''High Charity'' and decided that they needed to be more careful of the Sangheili "for the good of the Covenant".{{Ref/Novel|TCP|Page=347}}

====Finding the Ark's location====
[[File:RegretTruthH2A.jpg|thumb|250px|left|Regret suggesting that Truth "make an example" out of the Supreme Commander inside the [[Council Chamber]] (transmitting as a hologram) after the [[Battle of Installation 04]].]]
In [[2551]], a small Covenant team found a Luminary on [[Meridian]] after a [[Battle of Meridian|battle]] on the [[moon]], and the Luminary was delivered to Regret. By late [[2552]], two [[Steward]]s assigned to decrypt the Luminary finally revealed its content to Regret: the locations of the Halo rings and the place where the rings were created: [[Installation 00|the Ark]], along with the location of a [[Portal at Voi|device]] which would generate a [[slipspace portal]] to the Ark, where the Covenant believed they could begin their "Great Journey" by activating the [[Halo Array]]. When Regret asked where the Portal was located, the Stewards revealed it was on a planet called "[[Earth|Erde-Tyrene]]". Immediately after this revelation Regret, without informing the other Hierarchs, ordered [[Fleet of Sacred Consecration|all ships]] at his disposal (two [[CAS-class assault carrier|assault carrier]]s and thirteen [[Ket-pattern battlecruiser|battlecruisers]]) to go to Erde-Tyrene.{{Ref/Game|Id=beholden|H2A|Detail=''[[Terminal (Halo 2: Anniversary)|Terminal - Beholden]]''}} Unbeknownst to Regret, Erde-Tyrene was humanity's homeworld, Earth. Even before the Prophet of Regret learning the location of human's homeworld, the [[Prophet of Truth]] knew of the human presence on Earth after discovering the planet following the [[Fall of Reach]], and he had kept it, along with his personal plans for the planet and the Covenant, a closely guarded secret as he assembled a [[Truth's fleet|fleet]] of over 500 ships, but was ultimately [[Operation: FIRST STRIKE|delayed]] by the UNSC survivors of [[Reach]] and [[Battle of Installation 04|Installation 04]].<ref name="twenty">''[[Halo Waypoint]]'', ''"Ten Twenty"''</ref>

On his way to Earth, Regret was holographically present at the trial of the Sangheili [[Supreme Commander]] [[Thel 'Vadamee]] (later the new [[Arbiter]]) who was responsible for the loss of [[Installation 04]]. Regret helped condemn 'Vadamee and suggested that Truth "make an example" out of him.{{Ref/Level|H2|[[The Heretic]]}}

====Battle for Earth====
{{Main|Battle for Earth|Battle of Mombasa}}
{{Quote|Dear humanity, we '''Regret''' being alien bastards, we '''Regret''' coming to Earth, and we most definitely '''Regret''' that the Corps just blew up our raggedy ass fleet!|Sgt. Johnson to Miranda Keyes on Regret's message.}}
When Regret arrived near Earth on October 20, 2552, he quickly found himself greatly outnumbered by UNSC defenses. Instead of retreating, however, he sped towards the planet in religious fervor, sending forces to destroy the [[orbital defense platform]]s ''[[Malta Station|Malta]]'', ''[[Athens Station|Athens]]'', and ''[[Cairo Station (station)|Cairo]]'' so he could push through into the heart of Africa aboard his personal flagship, ''[[Solemn Penance]]''.{{Ref/Reuse|twenty}} Despite the [[John-117|Master Chief]]'s actions, his ship made it to the ground and deployed the first full-scale invasion force by the Covenant on Earth.<ref>'''[[Halo 2]]''', campaign level ''[[Cairo Station]]''</ref>

After landing in New Mombasa, Regret's forces searched the city for the Forerunner artifact, supported by [[Scarab]]s and many [[Phantom]] dropships. The humans, however, managed to [[Battle of Mombasa|rout Regret's forces in the city]], and also destroyed the remainder of his fleet, but not before his forces found at least some of the information they had been looking for. As the UNSC forces approached his carrier, Regret's ship initiated a [[slipspace]] jump in the middle of New Mombasa to [[Installation 05]]: from Regret's point of view, his troops had achieved their objective. The force generated by the jump heavily damaged the city. The move was so surprising that only the [[UNSC In Amber Clad|''In Amber Clad'']] and a few other UNSC ships were able to follow the carrier through the slipspace rupture.<ref>'''[[Halo 2]]''', campaign level ''[[Metropolis (level)|Metropolis]]''</ref><ref>'''Halo: Ghosts of Onyx''', ''page 185''</ref> Not long after Regret had left, an [[Truth's fleet|additional fleet]] sent by the Prophet of Truth arrived at Earth and deployed forces in Mombasa to pick up where Regret had left off.{{Ref/Reuse|twenty}}

Using data from the Luminary he had previously obtained at Meridian,{{Ref/Reuse|beholden}} Regret's jump took ''Solemn Penance'' and ''In Amber Clad'' to Installation 05.{{Ref/Reuse|Delta Halo}}

====Battle of Installation 05====
{{Main|Battle of Installation 05}}
[[File:RegretHoloH2A.jpg|250px|thumb|John-117 and Cortana observing Regret's sermon.]]
{{Quote|I shall light this holy ring, release its cleansing flame, and burn a path into the divine beyond.|Regret}}
Regret's carrier deployed ground and infantry forces onto the surface of [[Installation 05]], and set up a presence around a [[Temple (Installation 05)|temple]] in the middle of a lake, from which Regret began his religious sermons.{{Ref/Level|Id=Delta Halo|H2|[[Delta Halo]]}} He transmitted an apology to the [[Prophet of Truth]], indicating that he couldn't have known that the humans would be on Earth or in such force. Truth responded that only the [[Prophet of Mercy]] had spared him from public condemnation. Nevertheless, ''High Charity'' and the [[Second Fleet of Homogeneous Clarity]] rushed to the new Halo, and a flight of [[Kez'katu-pattern Phantom|Phantoms]] was deployed to retrieve the Hierarch.{{Ref/Level|Id=Regret|H2|[[Regret (Halo 2 level)|Regret]]}}

[[File:H2A JohnVsRegret.jpg|250px|thumb|left|John-117 reels his fist back to violently punch the Prophet of Regret.]]
''In Amber Clad'' arrived in the system soon after and deployed [[Orbital Drop Shock Trooper|ODST]] forces on Installation 05 along with the [[John-117|Master Chief]] to [[Assassination of the Prophet of Regret|locate and kill]] Regret. The operation was a success, with the Spartan breaking through Covenant defenses. John-117 and two [[Marines]] battled the Hierarch while fighting through waves his Elite [[Honor Guard|bodyguards]]. The Spartan was able to evade Regret's guards and board his [[Gravity Throne]], dispatching Regret with several punches to the head. Regret's Gravity Throne subsequently lost control and exploded. Soon afterward, the High Prophet of Truth ordered the Phantoms to return to ''High Charity'' and an [[CAS-class assault carrier|assault carrier]] to use its [[energy projector]] to destroy the temple.{{Ref/Reuse|Regret}}

====Part of the Flood====
[[File:H2A - RegretGravemind.jpg|thumb|250px|Regret as part of the Gravemind.]]
Regret's body was flung into the depths of the large lake surrounding the temple and later discovered by the [[Gravemind]] nested underneath the installation. His body was assimilated and reanimated by the Gravemind, although unlike many other Flood victims, he seems to have retained his individual consciousness even after his body had been completely absorbed by the Flood. After the Arbiter and John-117 were captured by the Gravemind, the Flood intelligence brought out Regret and the monitor [[2401 Penitent Tangent]] to demonstrate to the Arbiter the truth about the Halos. Regret was displeased to see Penitent Tangent and claimed that nothing could be done until his sermon was complete. However, Penitent Tangent denied this and accused Regret of knowing nothing about containment. Annoyed, Regret told the Arbiter that the Oracles were useless as they knew nothing about the Great Journey. Fed up with Regret and having made his point, the Gravemind lowered the High Prophet and monitor back where they had come from, causing Regret to scream in fear. The Gravemind, backed up by the Master Chief, told the Arbiter that Regret's Great Journey and Penitent Tangent's containment were the same and attempted to get the Arbiter to understand the truth about the [[Halo Array]].{{Ref/Level|Id="Gravemind"|H2|[[Gravemind (level)|Gravemind]]}} It was later thanks to Regret that the Gravemind discovered the location of the gateway to [[Installation 00|the Ark]].<ref name="wpregret">''Halo Waypoint'', ''"Regret"''</ref>

What remained of Regret was destroyed with the Gravemind when [[Installation 08|the replacement]] for [[Installation 04]] was prematurely fired by the Master Chief and [[Cortana]] at the conclusion of the [[Raid on Installation 08]].{{Ref/Level|H3|[[Halo (Halo 3 level)|Halo]]}}

==Personality and traits==
{{Quote|Nothing can be done until my sermon is complete!|Regret on activating Delta Halo, after being absorbed by Gravemind}} 
Regret has shown his reckless nature more than a few times. Being the youngest of the Hierarchs, he tends to act rashly without thinking; he adopted his aggressive and brash demeanor during his extensive service alongside the Sangheili in missionary and expeditionary affairs.{{Ref/Reuse|wpregret}}

His recklessness and failure to communicate with the other Prophets caused significant trouble for Thel 'Vadamee and the Prophet of Truth when he ordered his forces to deal with the humans at the Rubble and the Kig-Yar trading with them. Upon learning the location of the Ark, Regret sped to Earth with an insufficient, hastily assembled fleet without consulting with his fellow Hierarchs first. Even as he faced Earth's formidable defenses he persistently headed for what he thought was an easy way for unlocking the Ark. This foolish mistake eventually cost him his life on Delta Halo. Regret did apologize to the Prophets of Truth and Mercy for his reckless and failed attack on Earth, although he may have simply been trying to ''justify'' his actions to which Truth responded in kind, claiming that it was only thanks to Mercy that Regret "be spared of a public display" of their contempt.

Regret was very fond of the Sangheili and showed compassion towards them.{{Ref/Reuse|TCP}} He was not involved in the betrayal and massacre of the Sangheili as he died prior to the [[Great Schism]].{{Ref/Reuse|Regret}} Regret likely would have opposed it, as evident of Truth marking him as a moderate that needed to be eliminated, as well as a scapegoat to kickstart the Schism.

After his death by [[John-117]] and assimilation into the Gravemind, Regret showed no remorse for his actions against humanity however, and continued to preach the Covenant dogma, though he may not have been fully aware of his condition.{{Ref/Reuse|Gravemind}}

==Gameplay==
===''Halo 2''===
{{Main|Regret (Halo 2 level)/Walkthrough}}
[[File:H2ACampaign ChiefVsRegret.png|thumb|250px|Prophet of Regret [[Boss (gameplay)|boss fight]] in ''Halo 2''.]]
{{Quote|Incompetents! I'll kill it myself!|Regret, facing [[John-117]] in battle.}}
The only weapons that Regret had were his [[gravity throne]], seen in the level ''[[Regret (Halo 2 level)|Regret]]'', and his [[Type-25 plasma pistol|plasma pistol]]. Regret is heavily guarded by [[Grunts]] and [[Sangheili Honor Guardsman|Sangheili Honor Guardsmen]] of seemingly infinite numbers. The throne is equipped with two [[assault cannon]]s that glow bright orange and are a modified version of a [[Mgalekgolo|Hunter]]'s main weapon.

The gravity throne allows Regret to [[slipspace translocation|teleport]] a short distance away. The most effective way to deal with the Prophet is to jump onto his gravity throne and beat him to death with melee attacks. Energy swords and explosives will not kill the Prophet, though they can reduce the number of melee hits required to kill him. Projectile weapons, including the [[SRS99C-S2 AM Sniper Rifle|sniper rifle]], [[M41 rocket launcher|rocket launcher]], and [[Pez'tk-pattern fuel rod gun|fuel rod gun]], do not work on him. Although he will shout out and bleed when hit with other weapons, the player must still board his throne and punch him to death. This may take a few tries, especially if the player doesn't try to damage Regret with other weapons, since he can still teleport away while being punched.

===''Halo Wars''===
[[File:HWguide Regret.png|300px|right]]
{{Quote|Burn, heretics!|Regret, when using his Cleansing ability.}}

==Trivia==
{{Linkbox|quote=yes}}
*Regret is voiced in ''[[Halo 2]]'', ''[[Halo Wars]]'' and [[Terminals]] in ''[[Halo 2 Anniversary]]'' by [[Robin Atkins-Downes|Robin Atkin Downes]].
*Regret's title follows a broad trend of [[San'Shyuum|Prophet]] titles corresponding with their character's downfall. In the case of the Prophet of Regret, his title reflects his role in ''Halo 2'''s plot of immediately regretting his actions in attacking Earth without reinforcements, leading to his assassination by [[John-117]], which the [[Prophet of Truth]] surreptitiously abetted.
**He did, however, apologize to the other Hierarchs for attacking Earth with insufficient numbers, although he may have actually been attempting to justify his actions.
*If the player melees Regret's hologram in any level, the Master Chief will lunge towards the hologram, much like the Arbiter can lunge through the [[Sesa 'Refumee|Heretic Leader]]'s [[holo-drone]]. The lunge is more noticeable if the player uses an [[Type-1 energy sword|energy sword]].
*On holograms of Regret, if one stands on the holo-panel or crouch on it, it can be seen that Regret has real eyebrows, even though it is a hologram.
*When the Master Chief kills the Prophet of Regret on the level ''[[Regret (Halo 2 level)|Regret]]'', he will drop a [[plasma pistol]]. He held the same weapon in ''[[Halo: Contact Harvest]]'', and was rumored to keep it with him at all times in ''[[Halo: The Cole Protocol]]''.
*As of the 12th of May 2009, an update was released by Ensemble which made the Prophet of Regret slightly slower in ''Halo Wars'' Matchmaking, this was an attempt to stop "Leader Rushing".
*In the San'Shyuum section of the Covenant Species part of the ''Halo 3'' Manual, Regret is the Prophet seen in the picture.{{Ref/Game|H3|Detail=Manual, Covenant Species Section, page ??}}
