Battle of Koros Major
Satal Keto and his cousin Aleema had formed the Krath, a quasi-militant group whose principle power lay in the use of the Dark Side of the Force. The Krath managed to assert themselves into control positions on 6 of the 7 worlds in the Empress Teta system. The sole opposition was met on the planet of Koros Major. The Krath moved an ancient military space station into orbit around the planet, and began using military and Force-based attacks to turn the Korosians to their will. The Old Republic and the Jedi Knights, fearing another Dark Jedi uprising, created a combined strike force and went to Koros Major to turn the Krath back. The Krath used a series of Dark Side illusions to lull the Republic into thinking that the battle would be based mainly on the use of the Force, but an illusory armada of starfighters contained a percentage of real Chaos fighters, who crashed their starfighters into the command ships and disabled the Republic momentarily.
