The Yersinia is the flagship of the Odamas Fleet. The vessels origins are shrouded in mystery and its full capabilities are unknown. The ship acts as the fleets fighter and rigger carrier. Additionally, an automated factory and fuel processing plant were uncovered in the vessel and reactivated allowing the ship to produce and maintain new riggers and support vessels.

Another new capability that the vessel has demonstrated is some ability to regenerate Odamas Fleet operatives that have been killed. The exact nature of this process has not been explained and it does appear to cause some degree of memory loss in the regenerated individual.
