Battle of Chi Ceti
In 2525, the Battle of Chi Ceti was fought here between the and the Covenant warship Unrelenting, resulting in the first UNSC victory of the war. The facility on Chi Ceti IV was evacuated shortly thereafter, along with the MJOLNIR armor. In this battle, the Spartans successfully destroyed the Covenant ship, though Samuel-034 died in the process.

Human-Covenant War
Although the system was initially lost to the Covenant, Chi Ceti IV continued to be used by the Materials Group for research over the course of the Human-Covenant War; among several further developments by the Damascus facility was the MJOLNIR EOD variant.

Post War
The colony survived the Human-Covenant War and continues to support the UNSC by developing several MJOLNIR GEN2 armor variants.
