In 5 ABY, Grand Admiral Rae Sloane of the Galactic Empire ordered for assets to be directed to the D'Aelgoth sector. The Yomo Council, a faction that had formerly been part of the Empire, refused to follow Sloane's order, and Colonel Soran Keize of the Empire's 204th Imperial Fighter Wing subsequently listed it among a number of "treasonous actions" by the Yomo Council before his forces proceeded to destroy the council's forces at the planet Fedovoi End.
