000 Tragic Solitude

"Would it not be better for the galaxy to perish that it might be reborn, free from your kind and those others who share in your hostility?"

- 000 Tragic Solitude to Olympia Vale.

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

Biography
000 Tragic Solitude, who chose its name in the "dark times" after the reintroduction, was created with the spherical appearance of other monitors. However, over time, it found that form "unaccommodating", Solitude felt it needed to merge with the Ark in order to maintain it, later claiming that it was "one with it".

Battle of Installation 00
During the Battle of Installation 00 Solitude ordered its sentinels to prevent the Covenant from accessing the lower levels of the Installation. When 343 Guilty Spark, the monitor of Installation 04, attempted to gain access to the Ark's systems during the battle 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
"No, this is not vengeance. This is justice."

- Solitude on his plans.

With the damage done to its, and other Installations, Solitude felt the galaxy would be better off without humanity and the other violent species. It was for this reason Tragic Solitude decided to repair its Installation and activate the Halo Array.

When the crew was kidnapped by Guilty Spark, Tragic Solitude enlisted the aid of a mortally wounded UNSC soldier from one of the RCTs deployed by the ship, 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 on 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. After Vale had contacted Dr. Mann, Drifts Randomly infiltrated Solitude's central processes and completely severed the monitor from them. 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.
