000 Tragic Solitude

"343 Guilty Spark"

- 000 Tragic Solitude

000 Tragic Solitude was a Forerunner AI construct and the monitor of Installation 00.

Battle of Installation 00
When 343 Guilty Spark, the monitor of Installation 04, attempted to gain access to the Ark's systems during the Battle of Installation 00 in December 2552, Tragic Solitude addressed the former's lack of authority on the Ark and informed Guilty Spark that the facility housed the Librarian's archives of the Conservation Measure. When Guilty Spark continued to persist, Tragic Solitude threatened the monitor with the Ark's sentinels.

Post-war era
When the arrived to investigate the damaged Ark in the post-war era and sent remote contact teams to the surface, Tragic Solitude enlisted the aid of a mortally wounded UNSC soldier, Bobby Kodiak, in his plan to repair the Ark. Solitude heavily modified Kodiak's body with cybernetic components to the point he could control him and used him to initiate the activation of the Halo Array from the Ark in order to get someone one the other side to open the portal and allow Tragic Solitude to dispatch Retriever Sentinels to mine resources he needed to repair his installation. An expedition soon arrived and their ship, the Sangheili corvette Mayhem, was quickly shot down by Solitude's Retrievers. As the humans and Sangheili began to trek across the surface to the Ark toward the Citadel, Tragic Solitude used armigers as well as the fauna indexed at the Ark to attack them and to kidnap Olympia Vale. Solitude and Vale had a lengthy conversation concerning the AI's motivations, but Vale was unable to convince him to not send an army of Retrievers to mine Earth for raw materials. Meanwhile, elsewhere on the Ark, 000 Tragic Solitude killed ONI scientist Henry Lamb using a sentinel. Solitude eventually forced Vale to fight the cyborg created from Bobby Kodiak, but Vale managed to prevail and Solitude was destroyed by Bobby, who was freed from the AI's control after the other members of the group damaged Solitude's data arrays.
