SUMMARY
343 Guilty Spark started life as the human Chakas on Erde-Tyrene, now known as Earth. Chakas' experience with the Ur-Didact and IsoDidact eventually led to his mind being uploaded into the carapace of a Forerunner monitor, initially called Monitor Chakas, then 343 Guilty Spark. Guilty Spark was assigned to Installation 04, which he served on for nearly 100,000 years until its destruction at the Battle of Installation 04. After the Halo's destruction, he was captured by the Covenant, who led him to Installation 05 and later the Ark. Guilty Spark was instrumental in helping John-117 and the Arbiter defeat the Covenant at Installation 00, though he turned on the UNSC forces, killing Sergeant Johnson.
Guilty Spark was rediscovered by the UNSC Rubicon on Installation 00 in 2554, where he stole the ship and left the Installation for his own purposes. Three years later, Spark, with the memories of Chakas reawakened within him, was found by a salvaging crew led by Rion Forge and made a part of the crew of the Ace of Spades, helping in the hunt for the UNSC Spirit of Fire.
The Battle of Installation 04 was an engagement between the UNSC Pillar of Autumn and the Covenant Fleet of Particular Justice on and around the Forerunner megastructure known as Installation 04, or Alpha Halo, in the Soell system.
The Battle of Installation 05 was an engagement between the Covenant forces, including those that fled the Battle for Earth, High Charity, and the Second Fleet of Homogeneous Clarity, and the UNSC-allied forces, including the UNSC In Amber Clad led by Miranda Keyes, and the Fleet of Retribution led by the Arbiter Thel 'Vadam.
The Battle of Installation 00 was a major conflict between the forces stationed aboard the UNSC Forward Unto Dawn and Arbiter Thel 'Vadam's Fleet of Retribution, and the Covenant fleet loyal to the Prophet of Truth.
The Return to Installation 00 was an Office of Naval Intelligence mission undertaken by the UNSC Rubicon to return to the Ark following the Battle of Installation 00 and investigate the status of the facility in August 2554.
The Mission to Mount Kilimanjaro was a trek undertaken by 343 Guilty Spark, Rion Forge, and the crew of the Ace of Spades to find the Librarian and, in the case of Spark, gain access to the Domain in September 2557.
The discovery of Bastion was the culmination of a series of events involving 343 Guilty Spark and Rion Forge that led to the discovery of the Librarian’s shield world.
