In response to the second insurrection of Ker and its allies, the remaining Upyri Federation worlds (that opposed the insurrection) formed new coalition force in 2484 known as the Upyri Federation Peacekeeping Forces. It is primarily made up of the remaining Federation Naval forces, and the Marines that did not side with Ker at the start of the rebellion.
The goal of the Peacekeeping Forces is the obliteration of insurrectionist forces and the reunification of the Upyri Federation. During the year 2490 in Crimson Incarnate, they are in a galactic stalemate with the Empire of Ker. Neither side giving an inch in the massive conflict.
