Ussans

"We are prepared to die fighting beside Ussa 'Xellus, in the struggle against the Covenant. This is honor, and honor is meaning."

- The blood oath of Final Decision

The Ussans are a faction founded by Ussa 'Xellus in response to the Sangheili signing the Writ of Union with the San'Shyuum to form the Covenant in 852 BCE. They were rediscovered by a Covenant separatist resupply ship, Journey's Sustenance, in 2553. The clan lived on Shield World 0673, known to them as the Refuge or the Ussan Refuge, in the Ussan system. Upon the colony's settling, the Ussans had a population of slightly over 400. By 2552, their numbers had risen to 2,310. Due to their isolation and the limited resources of the Refuge, the Ussans' technological capability had regressed considerably over their history; they barely had the means to travel among the disparate sections of the Refuge and used less sophisticated types of weapon than the Covenant, such as burnblades and mec-missilers.
