Though Guilty Spark was originally believed to have been destroyed in the [[Raid on Installation 08]], smoldering pieces of him survived, badly damaged and recovered by the {{UNSCShip|Rubicon}}. After taking over the ship,<ref name="Primordium">'''[[Halo: Primordium]]'''</ref> he rebuilt himself as an [[armiger]] and began a search for the [[Librarian]], a search that would lead him to seek out a new path for himself with the crew of the ''[[Ace of Spades]]'' and going simply by '''Spark'''.{{Ref/Reuse|Renegades}}
 
After locating [[Bastion]], Spark decided to leave the ''Ace of Spades'' and become the caretaker of the [[shield world]], feeling that he didn't belong in the past or present, but outside of time. As a final gift to his friends, Spark helped [[Lessa]] and [[Niko]] with their future endeavors and repaired [[Little Bit]] to be the new shipboard AI of the ''Ace of Spades''. With [[Rion Forge]] and company gone, Spark departed with Bastion to an unknown location.<ref name="POL">'''[[Halo: Point of Light]]'''</ref>

===Creation===
===Creation===
Prior to the end of the [[Forerunner-Flood war]], 343 Guilty Spark was created from the mind of a human named [[Chakas]]. Born on [[Earth|Erde-Tyrene]], Chakas unwillingly became involved in the Forerunners' schemes, which eventually brought him to [[Installation 07]], a Halo under the control of the rampant AI [[Mendicant Bias]] which had defected to the [[Flood]]. Chakas' traumatic experiences on Installation 07, specifically his encounters with Mendicant Bias and the [[Primordial]], brought him to the point of mental breakdown and left his physical body mortally injured.

After retaking the Halo, the [[IsoDidact]], in an apparent act of compassion, decided to salvage Chakas' mind by transferring his pattern—including his personality and the complete record of his physical body—into the shell of a monitor. Numerous [[mind transfer|archived]] [[ancient humanity|human]] personalities retrieved by [[Composer]]s after the [[Battle of Charum Hakkor]] as well as other data pertaining to the [[Librarian]]'s work were also uploaded into his memory. The monitor known as Chakas was then assigned to serve as a record-keeper and aide for the Librarian.<ref>'''[[Halo: Primordium]]''' ''pages 356-357''</ref> He wished to look after the human populations on the [[greater Ark]]; this request was granted by the Librarian, who saw this as part of his recovery and a reward for his service.<ref>'''Halo: Silentium''', ''page 260''</ref>

When the Flood [[Battle of the greater Ark|attacked]] the [[greater Ark]] in the final days of the Forerunner-Flood war, the Librarian asked Chakas to save as many of her specimens as possible. He attempted to get help from other monitors but they were busy with the attack. The Librarian ordered him to take a {{Class|Gargantua|transport}} to [[Omega Halo]]. Here he witnessed the [[Ur-Didact]] use a [[Composer]] on the human population, composing hundreds of thousands of men, women, and children.<ref>'''Halo: Silentium''', ''String 31''</ref> The Librarian was initially grief-stricken, but soon was able to tell Chakas he had to find the [[IsoDidact]] and go to the [[Installation 00|lesser Ark]] and hide the remaining specimens there.

Using coordinates provided by the IsoDidact, he took his ship through the [[Faber|Master Builder]]'s secret [[slipspace portal]] to Installation 00. Amongst those rescued by Chakas were his old friends [[Riser]] and [[Vinnevra]].<ref>'''Halo: Silentium''', ''String 32''</ref>

Preceding the Halo Array's distribution across the [[Milky Way|galaxy]], Chakas was commanded by the [[Ecumene Council]] to abandon all connection with his former station. As the installation monitors were being given their new assignments aboard a Lifeworker vessel stationed over the lesser Ark, the IsoDidact met with Chakas for one final time and the two had a brief conversation before they parted ways. It was also here that the installation monitors received their final names, with Chakas being assigned the name 343 Guilty Spark by the IsoDidact. The IsoDidact asked Chakas if he would fire the rings, were it his decision; Chakas remained silent,<ref>'''Halo: Silentium''', ''pages 313-314''</ref> but would continue to ponder the Didact's question for the millennia to come. Over a hundred thousand years later, Spark would cite this query to [[John-117]], whom he had evidently mistaken for the IsoDidact.<ref name="twoB">'''Halo: Combat Evolved''', campaign level ''[[Two Betrayals]]''</ref>

From that point forward, Spark became the designated guardian and custodian of Installation 04.<ref>'''Halo: Combat Evolved Anniversary''' - ''[[Terminal (Halo: Combat Evolved Anniversary)#Terminal Two|Terminal 2]]''</ref> When the Array was activated, with Installation 04 being the first to fire, Spark received a signal from a nascent, previously-unknown civilization broadcasting its first transmission into deep space, and was saddened by the realization that they would be wiped out before they even had the chance to travel to the stars and make contact with other beings. At the same time, large portions of Spark's memory were automatically suppressed for the sake of compartmentalization as a precaution in the event the Flood and its ancilla-corrupting [[logic plague]] were to resurface. This caused him to forget much of his past life aside from the knowledge required in his duties as caretaker of Installation 04.<ref>'''Halo: Silentium''', ''pages 329-330''</ref>

After the firing of the Halo Array as a last resort against the Flood, 343 Guilty Spark was alone in a galaxy void of sentient life. During the eons he spent monitoring Installation 04, he began to display signs of [[rampancy]] due to crippling loneliness, especially after communications with the other Installations had ceased.

After two cycles of hibernation, Spark found that he had become bored; something he had not believed he, as a monitor, was capable of. Aware of the [[Rampancy|risks]] involved with losing operational focus, Spark began to divert his attention elsewhere. For his own amusement, he began experimenting on his Installation, ejecting entire sections of matter from the ring's surface into space, intending to later rebuild them.{{Ref/Reuse|terminal}}

Circa [[40,000 BCE]], an [[Unidentified alien vessel|alien vessel]] crash-landed in Installation 04's [[Sector 1215]]. Though anxious to find answers for whether the Forerunners' plan to reseed life in the galaxy had been successful, Spark acted in accordance with protocol, blocking the distress signal sent out by the ship and not attempting to make contact with any possible occupants. No lifeforms exited the wreckage and the distress signal eventually terminated, offering Spark no answers. Afterwards, the monitor had a containment sarcophagus constructed around the ship. Disappointed by his failure to learn about the outside galaxy, Spark resolved to be more flexible in his adherence to protocol should outside life ever encounter his ring again.<ref>'''Halo: Combat Evolved Anniversary''' - ''[[Terminal (Halo: Combat Evolved Anniversary)#Terminal 6|Terminal 6]]''</ref>

During his long isolation, Spark had little to no contact with other intelligent beings, and spent most of his time maintaining his installation. However, over time, Spark observed one or more spacefaring species visit Installation 04. These species landed on and explored the ring, recorded their findings and eventually left without breaching Flood containment.<ref name="cftu">'''[[Conversations from the Universe]]''', ''343 Guilty Spark's Log''</ref> These interactions did not please Spark, leading to him threatening anything that came near the installation.<ref name="h2a term 1">'''[[Halo: Combat Evolved Anniversary]]''', ''[[Terminal (Halo: Combat Evolved Anniversary)#Terminal One|Terminal 1]]''</ref>

After over one hundred thousand years without a major incident, Spark was faced with a crisis when the {{UNSCShip|Pillar of Autumn}} discovered Installation 04, pursued by the Covenant [[Fleet of Particular Justice]]. Fearing a containment breach, Spark warned the ship to jump at least one light-year away from the Installation or be destroyed. After remotely accessing the ship's systems, however, Spark realized that the ship was manned by [[Reclaimer]]s after finding data on human history. He then deactivated the ring's defensive systems and instructed the ship to a docking facility - the ''Pillar of Autumn'' crash-landed on the ringworld shortly afterwards.{{Ref/Reuse|h2a term 1}}

During the subsequent UNSC-Covenant [[Battle of Installation 04|guerrilla war]], Covenant troops stumbled upon a [[Flood containment facility]], and after unwittingly deactivating the structure's containment measures, they unleashed the long-dormant [[Flood]] that had been stored inside. As per his protocols, Spark began to search for a Reclaimer to activate the installation, and came upon UNSC [[Staff Sergeant]] [[Marvin Mobuto]]. Using the Installation's [[slipspace translocation]] [[Teleportation grid|grid]], Spark brought Mobuto to the [[Library]] in an effort to retrieve the Activation Index. Ultimately, the ill-equipped Marine was overwhelmed and killed by the Flood, forcing the Monitor to seek out another Reclaimer. Spark and a squad of [[Sentinel Aggressor|Sentinels]] moved to the Flood containment facility, where they encountered a group of UNSC [[UNSC Marine Corps|Marines]] and [[John-117]], who were battling the Flood outbreak.

Taking the Index for safe keeping, Guilty Spark teleported himself and the Master Chief back to the [[Control Room]].<ref>'''[[Halo: The Flood]]''', ''page 253''</ref> The Monitor explained that activation protocols forbid him from personally uniting the Index with the Core to activate the ring; only a Reclaimer could be permitted to do so.<ref>'''[[Halo: The Flood]]''', ''page 255''</ref> Spark gave John the Index, and urged him to activate the Installation.

With the Index in the possession of a hostile [[Artificial intelligence|AI]] and protected by a now uncooperative Reclaimer, the Monitor turned the Sentinels against the Master Chief in order to retrieve the Index. John-117 and Cortana escaped with the Index, with Spark and his Sentinels in pursuit. During their escape through the Control Room's adjacent tunnels, Master Chief disabled the three [[phase pulse generator]]s, forcing their repair and delaying the Installation from firing in the near future. Disappointed, the Monitor followed John-117 and Cortana to the ''[[UNSC Pillar of Autumn|Pillar of Autumn]]'', which they planned to detonate in order to destroy the ring. Intrigued by the abundance of knowledge within the ship's data banks, Spark briefly put aside his concerns for the Installation and began downloading information from the ''Autumn'''s computers, being especially interested in the sections pertaining to human history. He then disabled the vessel's automated self-destruct system to preserve the repository of knowledge he had discovered.

Although the warship's engineering room was protected by many Sentinels, the Master Chief was successful in destabilizing the power cores. Realizing the implications of the ship's destruction, the Monitor immediately fled the doomed ring. Moments before the ring was destroyed, the Monitor consoled himself by asserting that he had done his utmost to fulfill his responsibilities. Later upon further reflection, when he was floating through space, Guilty Spark found himself happy as, ultimately, his purpose had been fulfilled: the Reclaimer had indeed succeeded in stopping the outbreak, even if it had been done in an "inelegant" fashion.{{Ref/Reuse|cftu}}

Later upon further reflection, when he was floating through space, Guilty Spark found himself happy as, ultimately, his purpose had been fulfilled: the Reclaimer had indeed succeeded in stopping the outbreak, even if it had been done in an "inelegant" fashion.<ref name="cftu"/>

Such a state of affairs could not be tolerated for long by the Covenant and soon action was taken to eliminate the Heretics. This was accomplished quickly and quietly by the [[Thel 'Vadam|Arbiter]] and a team of special operations troops. Ironically, the Arbiter was Thel 'Vadamee, the very Sangheili 'Refumee believed could be trusted with Guilty Spark's revelations. The Arbiter was surprised by the appearance of an "Oracle," but rather than allow Guilty Spark to tell him the truth, 'Refumee used Guilty Spark's appearance as a distraction to attack and was killed by the Arbiter, taking with him all that he had learned from Guilty Spark. In the aftermath, Guilty Spark was captured by [[Tartarus]] and given to the Prophets aboard [[High Charity]].<ref>'''[[Halo 2]]''', campaign level ''[[The Oracle]]''</ref>

In the aftermath, Guilty Spark was captured by [[Tartarus]] and given to the Prophets aboard [[High Charity]].
Interrogated by the [[High Prophets]], Guilty Spark revealed the nature of the installations and the means to employ them, which made the Prophets send the Arbiter to retrieve [[Installation 05]]'s "Sacred Icon".<ref>'''[[Halo 2]]''', campaign level ''[[Sacred Icon]]''</ref> Guilty Spark may have attempted to educate the Prophets to the truth as well without success as the [[Prophet of Regret]] would later complain that the "Oracles" were useless and knew nothing about the Great Journey while meeting with the [[Gravemind]], Arbiter, [[John-117|Master Chief]] and [[monitor]] [[2401 Penitent Tangent]].<ref>'''[[Halo 2]]''', campaign level ''[[Gravemind]]''</ref> After the Index been obtained, Tartarus took Guilty Spark and the Index to Installation 05’s [[Control Room]], using [[Miranda Keyes]] as the new [[Reclaimer]]. However, Tartarus grew tired of Guilty Spark's constant warnings.

Guilty Spark's revelations about the truth of the installations and what become of the Forerunners confirmed what the Arbiter had already learned from the Gravemind and Master Chief and completely ended his faith in the Covenant religion. However, the [[Brute]]s were too loyal to the Prophets to accept the truth that the Halos were weapons of mass destruction. Tartarus used Guilty Spark as a weapon, throwing the helpless monitor at Johnson so Tartarus could fire the rings. Guilty Spark observed the ensuing struggle, reminded of the one he had witnessed on the ''Pillar of Autumn''. Keyes sought Spark's advice on how to shut the installation down and eventually got him to admit that simply removing the Index would suffice.

After [[Tartarus]] and his [[Brute Captain]]s were killed, Keyes managed to deactivate the installation the control panel for the installation began to show a holographic display. Guilty Spark, after being used by Johnson as a ride to the lower level, translated the display to Johnson, Miranda Keyes, and the Arbiter: the rings were now on standby, meaning they could be activated simultaneously from [[Installation 00|the Ark]]. The Arbiter asked Spark where it was, and he provided them with coordinates to where he believed it to be located; unbeknownst to him, it turned out to be [[Earth]], the human homeworld.<ref>'''[[Halo 2]]''', campaign level ''[[The Great Journey]]''</ref><ref>'''Halo Encyclopedia''', ''page 197''</ref><ref>'''Halo 3''', campaign level ''[[The Ark]]'' ("''I always assumed it was part of a…shield installation, but it seems I was mistaken.''")</ref>

Later that day, Guilty Spark and his allies rendezvoused with [[Rtas 'Vadum]] and the newly-formed [[Fleet of Retribution]]. Together, they formulated a plan for sterilization and quarantine. While the Arbiter, Keyes, and Johnson left Delta Halo for Earth, Guilty Spark remained behind to help coordinate containment efforts with 'Vadum and the fleet. On November 4, they, along with any friendly Elite ships would begin a campaign to cauterize the surface of the ring, destroying anything that attempted to slip away.<ref>'''Halo Waypoint''', [[Eleventh Hour reports|Eleventh Hour report 5]]</ref><ref>'''[[Halo Waypoint]]''', ''"The Long Road Home"''</ref>
After [[Tartarus]] and his [[Brute Captain]]s were killed, the control panel for the Installation began to show a holographic display. 343 Guilty Spark translated the display to Johnson, Miranda Keyes, and the Arbiter. The rings were now on standby, meaning they could be activated simultaneously from [[Installation 00|the Ark]]. The Arbiter asked Spark where it was, and he directed them to a specific location, which turned out to be [[Earth]], the human homeworld.


At some point during the blockade, a single [[Indulgence of Conviction|Flood-controlled cruiser]] escaped containment and headed for Earth. Guilty Spark joined part of the fleet as it gave chase.
On November 3rd, 2552, Spark was involved with assisting and coordinating efforts with [[Rtas 'Vadum]] and the [[Fleet of Retribution]] in cleansing the surface of Delta Halo of the Flood while Johnson, Keyes, and the Arbiter traveled back to Earth to warn humanity of the coming [[Battle of Earth#Truth's arrival|Covenant reinforcements]]. When a single [[Indulgence of Conviction|Flood-controlled cruiser]] escaped containment, twelve ships of the Fleet of Retribution gave chase, among them the [[CAS-class assault carrier|assault carrier]] ''[[Shadow of Intent]]''.<ref>[https://www.youtube.com/watch?v=8K3hG76Ctmo '''YouTube''': ''The Long Road Home'']</ref>

On November 17, Guilty Spark and the Fleet of Retribution arrived over the [[Kenya]]n town of [[Voi]], minutes after the infested cruiser crash-landed there. The Elites believed that the Flood vessel contained Cortana, last seen trapped on ''High Charity'' with the [[Gravemind]]. As Master Chief recovered the data module that stored her, Guilty Spark arrived in time to assist, destroying a Combat Form about to attack the Spartan and attempting to begin repairs on the unstable module. After a tense exchange between the two former enemies, they put aside their past and proceeded to bring the device back to their ship, where Guilty Spark completed his repairs. It turned out that the device did not contain Cortana, but was merely a [[Covenant storage device|data core]] storing a holographic message from the AI. In her message, she claimed she had discovered a way to stop the Flood without activating the other Halo rings but it required them to travel to the Ark. In order to discover the answer, the Chief, Johnson, Keyes and the Arbiter, along with Covenant separatist forces traveled through the recently-opened [[Portal at Voi]] and Guilty Spark joined them.{{Ref/Reuse|Floodgate}}
343 Guilty Spark and the Fleet of Retribution arrived on Earth shortly after a Flood-captured ship crashed into Voi. They learned that the Flood vessel contained Cortana, last seen trapped on ''High Charity'' with the [[Gravemind]]. As Master Chief recovered the data module that stored her, Spark arrived in time to assist, destroying a Combat Form about to attack the SPARTAN and attempting to begin repairs on the unstable module.

In order to discover the answer, the Chief, Johnson, Keyes and the Arbiter, along with Covenant separatist forces traveled through the recently-opened [[The Portal|Portal]]; Spark joined them.


The fleet followed the Covenant forces through the portal, and arrived at [[Installation 00]] - the real Ark. Largely unaware of the details of the Ark due to the compartmentalization protocols limiting his data stores, Guilty Spark aided the Reclaimers in their exploration of the Ark with enthusiasm. Guilty Spark's attempts to gain further access to the Ark's systems, however, prompted a response from the installation's [[000 Tragic Solitude|custodian ancilla]], which threatened Guilty Spark with lethal force if he persisted.<ref>'''Halo 3''', ''Terminal 3''</ref> Searching for [[Prophet of Truth|Truth]]'s location, the Sangheili located the Installation's [[Cartographer]]. Guilty Spark followed the Chief and the Arbiter's platoons to penetrate the wall protecting the location, opening doors and providing Sentinels as backup for the assault. Once the Cartographer was found, Guilty Spark used the map system to pinpoint the Prophet of Truth's location, but noted that the location was shielded by an energy barrier. As he studied the map, Guilty Spark was surprised to notice [[Installation 08|a Halo ring]] in the Ark's [[Foundry (location)|Foundry]], but didn't have time to express his discovery. At that moment, a loyalist Phantom arrived, driving the trio back deeper into the hallways. Guilty Spark led them towards Johnson's location a few floors below. After the reunion, Johnson was nervous at the sudden appearance of hundreds of Sentinels, but Guilty Spark reassured him that they meant no harm and were part of a primary task force, although he couldn't discern their goal.<ref name="The Ark">'''[[Halo 3]]''', campaign level ''[[The Ark]]''</ref>

UNSC and Sangheili forces moved to disable the shield barrier protecting Truth. However, as soon as the barrier was taken down, ''[[High Charity]]'' suddenly transitioned out of Slipspace above the area, nearly destroying Rtas 'Vadum's ship, and peppered the Ark with Flood dispersal pods and flaming debris. Terrified of a complete Flood takeover, Guilty Spark insisted that they focus their attention on the Flood. He was met with opposition from Keyes and the Sangheili leaders, who made it clear that their first priority was to kill Truth before dealing with the parasite.

Once the Prophet of Truth was dead and the threat of the Halo Array neutralized, the Flood began their infestation of the Ark under the command of the Gravemind. Having escaped the Flood, Master Chief and the Arbiter discovered the new Halo ring rising from the Ark's Foundry. Noting Guilty Spark's nearby presence, the Master Chief questioned how long the monitor had known. Guilty Spark admitted that he'd only known for sure at that moment, but he had hoped he was right about the replacement's existence. To Guilty Spark's pleasure, the Master Chief stated that he planned to fire the ring, and Guilty Spark happily set about preparing the ring for its firing while the Master Chief traveled to ''High Charity'' to rescue [[Cortana]] who still had the Index from [[Installation 04]].{{Ref/Reuse|The Ark}}<ref name="Cortana">'''[[Halo 3]]''', campaign level ''[[Cortana (level)|Cortana]]''</ref>
Once the Prophet of Truth was dead and the threat of the Halo Array neutralized, the Flood began their infestation of the Ark under the command of the Gravemind. Spark met with the Arbiter and the Master Chief after their initial escape, and discovered that the Ark had been constructing [[Installation 04B|a new Halo ring]] to replace Installation 04. John stated that he planned to fire the ring, and Spark happily set about preparing the ring for its firing.


After rescuing Cortana from the Flood-infested ''High Charity'', Master Chief, the Arbiter and [[Sergeant Major]] Johnson landed on the newly constructed Halo. Guilty Spark aided their progress through the Installation by providing Sentinels to combat the Flood. Once the initial wave of Combat and [[Pure forms]] were destroyed, Guilty Spark opened the main blast door to the Control Room.<ref name="Halo">'''[[Halo 3]]''', campaign level ''[[Halo (Halo 3 level)|Halo]]''</ref>

Spark was reunited with the Chief along with Johnson and the Arbiter in the new Installation 04's control room, where he informed them that the ring was almost complete, but not yet ready to fire. However, despite Spark's panicked warnings that a premature activation would result in the destruction of the Ark (and, more importantly to Spark, the new Halo ring), Johnson ignored him, determined to destroy the Gravemind and the Flood once and for all. Unable to accept that his new installation was about to be destroyed, an enraged Spark fired upon Johnson as he attempted to activate the ring, mortally wounding him. Seeing John run towards his fallen comrade, the Monitor then fired upon him and the Arbiter, knocking the Arbiter out of the room and sealing the door behind him. The Master Chief was left to face the Monitor alone.

With the Chief wounded and his shields down, Spark declared that he would stop at nothing to follow protocol and ensure the safety of the ring and the Ark. The Chief engaged Spark in combat, but was unable to damage the Monitor's housing. Johnson, burned and bleeding but still conscious, used his [[M6 Grindell/Galilean Nonlinear Rifle|Spartan Laser]] to damage Spark before he could kill John, cracking the AI's protective casing. Johnson then gave his weapon to Spartan. Spark began to malfunction ever more erratically as the battle progressed, and after three more blasts from the Spartan Laser, he finally lost all structural integrity and exploded.

As a result of the extensive damage he had sustained, Spark's memory was heavily splintered and barely functional; for example, he was unable to remember many of the preceding events, only learning of his recent interactions with the humans after tapping into their records. Spark explained that his mind had fragmented into a number of different identities over time and the incarnation previously encountered by the UNSC was merely one of his many selves.

===Search for the Librarian and new friends===
Spark first attempted to take the {{UNSCShip|Rubicon}} to the [[shield world]] known as [[Trove]] to get an [[upgrade seed]] to better help prepare the ship for the journey ahead, unaware that the shield world had been destroyed in [[2531]] by the {{UNSCShip|Spirit of Fire}}. However, there were complications following Spark taking control of the ''Rubicon'' and the ship crashed on the planet [[Geranos-a]] in the [[Ibycus system]]. Spark survived by creating an [[armiger]] for himself out of parts salvaged by the crew from the Ark, but the crew died in the crash. Spark buried the crew in a mass grave and sent out a distress signal.

The recovery of a data drop in late [[2555]] containing the story Spark told the ''Rubicon'' crew as well as the recovery of the [[Halo: Cryptum|Bornstellar Relation]] on [[Sarcophagus]] made ONI determined to capture and torture Spark for all of the information they could get on the Forerunners and the Librarian. In [[2557]], Spark's distress signal was picked up by a cargo ship and relayed to ONI, but Spark was recovered by the salvage ship ''[[Ace of Spades]]'' first. Having repaired, combined or jettisoned most of his personality strings while trapped, Spark only retained the personalities of Chakas and 343 Guilty Spark. As a result, he adopted a more cooperative mindset where, while he was determined to complete his mission and not be imprisoned again, he would work with the ''Ace of Spades'' crew. Spark offered to help the crew recover their stolen salvage if they helped him find the Librarian, which they eventually agreed to. [[Niko]] later aided Spark in creating an avatar which enabled him to appear throughout the ship in holographic form rather than rely on using his armiger to interact in person.
 
After a failed attempt to get an upgrade seed from the Etran Harborage and revealing the same story to the crew as he did the ''Rubicon'', Spark took the ''Ace of Spades'' to the [[Forerunner]] planet of [[Triniel]], whose population had committed mass suicide during the [[Forerunner-Flood war]] rather than let the Flood overtake them. Spark was able to get the [[slipspace flake]] he needed and created the upgrade seed. Though Spark initially activated the planet's communications satellites which would draw attention to it, he agreed to Rion's wishes and shut them down again so that the planet would forever remain lost, an undisturbed tomb of those who died there. Spark later attempted to access the [[Domain]], but was denied access by [[Catalog]], though he learned that [[Ur-Didact|the Didact]] had tried the same and also failed. Before disconnecting completely, Catalog told Spark that what he sought was not lost, it was already written and Spark just had to find it.
 
In order to enact their plan, the ''Ace of Spades'' crew reluctantly let Spark upgrade their ship so they could match an ONI [[Prowler]] when it came for them. As part of the plan, Spark uploaded a splinter of his 343 Guilty Spark persona to a data core that was traded to ONI. However, when the crew came into danger, Spark exposed himself to rescue them. With the ''Ace of Spades'' new upgrades and with Spark having upheld his end of the deal, the crew [[Mission to Mount Kilimanjaro|took him]] to [[Mount Kilimanjaro]] where Spark used the fragment of himself in the data core to shut down the ONI base at the [[Portal at Voi]], and search for information on Catalog's intrusions and the expired Catalog found on the African savannah. Beneath Kilimanjaro, Spark led the crew to a [[Lifeworker]] pod before revealing to Rion what he'd known for most of the time they were together: [[John Forge|her father]] had died destroying [[Trove]].
 
With the crew surrounded by [[Fireteam Apollo]] and an ONI team, Spark deactivated the [[light bridge]] for the crew before he entered the hard light beam around the pod and awakened a [[mind transfer|personality imprint]] of the Librarian stored within. The Librarian caused Spark to appear as he did when he was [[Chakas]] and addressed him by his human name. The Librarian expressed sorrow for the pain she had caused her old friend and told him that Spark was a singular marvel: a being that had adapted and evolved on its own, a product of necessity, but one that may have a great impact on things to come. The Librarian briefly told Spark of the awakening of her imprint on [[Requiem]] as well as that of the Didact, but did not elaborate further though Spark realized from her reaction that the Didact's threat was "not worrisome." The Librarian recognized that there were two sides within Spark: one that didn't care and was cold and scheming while the other cared and was all heart.
 
Spark claimed to have no heart and asked about his friends [[Riser]] and [[Vinnevra]]. The Librarian recognized Spark's desire to bring back his friends and reminded him of his own experiences carrying the imprint of [[Forthencho]], Lord of Admirals. The Librarian told Spark that his friends were at peace, their gene song quiet. Spark requested to be sent to the Domain where they were remembered, however, the Librarian cautioned against such a move, and when Spark then asked her to walk amongst the living as he did in an armiger, the Librarian refused, as she felt it was not time yet. The Librarian helped Spark to see that he had found friends again in the crew of the ''Ace of Spades'' who were in grave danger.
 
The Librarian stated that she would go to join her other personality imprints at the [[Absolute Record]] while humanity had to be given the tools to uphold the Mantle and the knowledge to tend to the Domain. The Librarian offered Spark a choice: to remain with his friends or to go with her to the Absolute Record. The Librarian gave Spark a small etched box that she called a key for if he chose to remain and instructed that he "find what's missing. Fix the path. Right what my kind has turned wrong." After the Librarian admitted that the Didact was most likely beyond redemption, Spark announced his decision to stay with the friends he had waited one hundred thousand years to find and promised to meet the Librarian again before she departed for the Absolute Record. As she left, the Librarian communicated with Rion at least and in her message, the Librarian instructed Rion to take care of Spark who is more fragile and important than she could ever know.<ref name="Renegades">'''[[Halo: Renegades]]'''</ref>
 
===A new path===
{{Quote|I have waited one hundred thousand years to find my friends. Why would I leave when I have found them?|Spark chooses a new path.<ref>'''[[Halo: Renegades]]''', ''page 298''</ref>}}
Upon emerging from the hard light beam, Spark shifted his [[armiger]] into a combat configuration with a hard light rifle which Spark used to bring down the roof of the cavern and force the Spartans to retreat. Spark led the crew onto the platform where the Librarian's pod had been which also acted as a [[slipspace translocation|translocation pad]] and teleported everyone to safety outside where Spark was able to remote-pilot the ''[[Ace of Spades]]'' to pick them up and cloaked them from military detection while pulling his fragment from the ONI systems.
 
Awhile later, after Rion woke up, Spark approached her to offer an explanation for his lies regarding [[John Forge]]'s fate. Spark explained that he could not bear to bring her the pain of the truth and explained that he had gained much data from the species of the [[Covenant]] and humanity during his interactions with them. When Spark came aboard the ''Ace of Spades'', he went through its data and the name of the {{UNSCShip|Spirit of Fire}} had triggered an echo of memory that had taken Spark several days to figure out. Spark revealed that the ''Spirit of Fire'' had preprogrammed maintenance sheds and data drops in hopes of leaving a trail and in those, [[Serina]] had left a message for Rion as part of a promise to her father from the AI and the captain. Spark was then able to provide Rion with her father's message.
 
A week later, the crew holds a funeral for John Forge with Spark singing and using it to let go of his friends. Confronted by Rion, Spark admitted his desire to access the Domain with the Librarian's help to find the ghosts of his friends and bring them back or join them before everything that had happened changed his mind. Spark would only state that the Librarian had given him a coordinate key to a safe place and volunteered to act as the new shipboard AI of the ''Ace of Spades'', promising that there would be no more lies.
 
After they departed Earth, the crew discussed their options with [[Gek 'Lhar]]'s bounty still on their heads and ONI after them because of Spark. Rion decided to continue their mission to find the ''Spirit of Fire'' which Spark expressed confidence that they would find. The crew decided that they would have a wealth of options to choose from after that and each raised a toast with Spark's being "to friends."{{Ref/Reuse|Renegades}}

After a hundred thousand years of isolation, 343 Guilty Spark was quirky, detached and analytical. For Spark, protocol dictated all; the slight emotion he showed for the death of an ally was truly grief only for the inconvenience of finding another to assist him. While he gladly assisted those who requested his help, if his allies decided to prevent him from completing necessary actions - such as the firing of his ring - he would turn on them without hesitation and dispatch them with lethal force.

Tens of thousands of years of monotonous duty spent monitoring his installation and waiting for a Reclaimer appeared to have had a significant effect on the Monitor's sanity. Spark showed many characteristics of rampancy. He loved to learn and to take records, even in the face of his installation's imminent destruction; accessing the ''Pillar of Autumn'''s shipboard databases, he was intensely fascinated about finally having access to human history up until that point, referring to the record as "all of our lost time."<ref>'''Halo: Combat Evolved''', campaign level ''The Maw''</ref> He also showed other odd behaviors such as humming and singing. Typically, he was also untroubled with matters of life or death. When Sesa 'Refumee and Tartarus were killed by the Arbiter, he appeared casual, although he was remorseful when Sesa 'Refumee was killed. Spark's detachment resulted in a tendency of rarely giving more information than he had to. For example, on Installation 04 he merely told John-117 that activating the ring would stop the Flood, neglecting the portion about how all life in range of the ring would be wiped out to do so (although he may have been genuinely unaware that the Master Chief was completely oblivious to any of this, assuming the Spartan to be the [[IsoDidact]]).<ref>'''Halo: Combat Evolved''', campaign level ''Two Betrayals'' (343 Guilty Spark: ''"But you already knew that... I mean, how couldn't you?" ... "Why would you hesitate to do what you have already done?"'')</ref> Likewise, he did not tell the High Prophets that the ring was a weapon when asked about the location of Installation 05's Index, only telling that truth to the Covenant when asked directly by the Arbiter. While bound by protocol, Guilty Spark seemed to genuinely enjoy the prospect of firing the Halo Array, unlike his fellow Monitors such as [[049 Abject Testament]].

Although created from the essence of [[Chakas]], 343 Guilty Spark became his own entity after his conversion into a monitor, often referring to his past human self as a separate being despite retaining Chakas' memories. This was the result of a number of factors, including the combined wisdom of the numerous human essences stored within his reborn self, the immense amounts of added knowledge and programming to enable him to effectively perform his duties, as well as the mental trauma Chakas suffered in his human form; he himself stated that he "went mad". The suppression of most of his memories and knowledge upon his assignment to Installation 04 in the name of compartmentalization further diverged him from his original self, in addition to his primary personality array splintering to numerous fragments over tens of thousands of years. However, many of his ancient memories from prior to his post at Alpha Halo resurfaced after his physical shell was severely damaged and subsequently reactivated by a UNSC science team for interrogation; thus, this entity was closer to his original persona of Monitor Chakas than his previously-encountered incarnation hamstrung by compartmentalization protocols.{{Ref/Reuse|p372}}

As a Forerunner AI, 343 Guilty Spark possesses highly advanced abilities with electronic systems; even in his highly reduced, damaged state, he was capable of effortlessly breaching the numerous firewalls and other safeties of the {{UNSCShip|Rubicon}}, a highly secure ONI vessel. In the conclusion of the interrogation, he subdued the ship's AI and took complete control of the ship, having uploaded his data stream into the ship without the crew initially noticing. As with [[United Nations Space Command|UNSC]] and [[Covenant]] artificial intelligences, Guilty Spark's programming prohibited him from carrying out certain actions. He cannot, for example, retrieve the [[Activation Index]] from the [[Library]] or use it to activate Installation 04, instead requiring a [[Reclaimer]] to carry out this task.{{Ref/Reuse|343GS Final Cutscene}}

Spark's protocol bound him only to contain a Flood outbreak from Installation 04, so when Installation 04 was destroyed, his directives were also terminated. This means that he no longer had a priority prescribing his actions concerning the Flood - he was free to make choices concerning the Flood, as he did on Installation 05 when he assisted in the deactivation of its firing sequence, risking the containment of a Flood outbreak. According to Spark, the loss of his ring left him with only one purpose: to aid the Chief as a Reclaimer, which Spark admitted was something he should have done from the beginning instead of trying to hinder him. This caused the two to put aside their differences and Spark to join forces with the Chief again against the Flood and the Covenant. Due to his abilities in connection with the Halo Array, Spark proved to be a powerful ally and seemed to take commands from Commander Keyes, Sergeant Johnson and the Master Chief without hesitation as part of his new function in life. When he discovered [[Installation 08]], his priority protocol reactivated, and he adopted the ring as his replacement. When [[Sergeant Major|Sgt. Maj.]] [[Avery Johnson|Johnson]] declared his intent to fire the Halo, which would destroy it, Spark unhesitatingly killed him. Despite his treachery, it is unlikely the UNSC would have been able to prevent the premature activation of the Halo Array without Guilty Spark's assistance.
 
After three years trapped on [[Geranos-a]], Spark was able to repair, combine or jettison many of his personality strings until only Chakas and 343 Guilty Spark remained. After being rescued by the ''[[Ace of Spades]]'', Spark found himself remembering more and more of what it was like to be human and found himself horrified at what he had become as 343 Guilty Spark. Spark adopted a personality that was something of a mix between the two while acknowledging his past mistakes, at one point telling the ''Ace of Spades'' crew that he didn't make a good impression upon the human military while he was a monitor and neither did others of his kind.
 
Instead of going by Chakas or 343 Guilty Spark, he preferred to simply be called Spark, a nickname given to him by the crew of the ''Ace of Spades''. After his encounter with the [[Librarian]]'s personality imprint, Spark gave up his efforts to bring back or rejoin his old friends, instead accepting that the ''Ace of Spades'' crew were the friends he had been searching 100,000 years for. Spark showed compassion for [[Rion Forge]], refusing to tell her the truth about her father at first not just so that she wouldn't stop helping him, but because he couldn't bear to bring her the bad news. After telling her the truth, Spark did her a further kindness by giving Rion the message he had discovered recorded by John Forge for her. Additionally, while he at first planned to use the communications satellites on [[Triniel]] to communicate with the [[Domain]], Spark stopped them from rebooting when it was realized that doing so would draw attention to the long-lost planet. In doing so, Spark showed compassion for the hundreds of millions that committed mass suicide on Triniel to avoid falling victim to the Flood by leaving the planet untouched by further mass exploitation, something that the human crew also wanted for the planet. As Spark, he seemed to have lost much of the violence he possessed as 343 Guilty Spark, purposefully aiming to collapse a cavern in a way that would not harm anyone as a distraction rather than using his formidable firepower to try to kill attacking enemies as he did with Johnson and the Master Chief on [[Installation 08]].


Having accepted his new purpose, Spark was happy to settle into life as the ''Ace of Spades'' shipboard AI. The Librarian herself called Spark a singular marvel, a being that evolved on his own out of necessity and one that may have a great impact on things still to come. While speaking with Rion, the Librarian asked her to take care of Spark as he is more fragile and important than she could ever know.{{Ref/Reuse|Renegades}}

*In the [[Halo (Halo 3 level)|final level]] of ''Halo 3'', just before 343 Guilty Spark dies, he will make random statements such as Gollum's catchphrase from Lord of the Rings: "My Precious!" This is likely because Halo is also a "ring of great power", just like the Great Ring that Gollum possessed. Other similarities to the Lord of the Rings include that Guilty Spark is an ally for most of the third game, but turns against the main characters at the end, dying to try and stop the protagonists from destroying his beloved ring.
