War against Celestial client species

Following the Rakatan revolt against the Celestials, the Infinite Empire of Rakata waged devastating war against their rivals among the Celestial client species, namely the Killiks, the Gree Empire and the Kwa holdings. At some point, they had driven back the Gree to their home cluster and all but exterminated the Kwa. The Inner Rim planet of Oaka Prime was designated as a wildlife preserve to serve as a refuge away from the war.
