A struggle over land and resources unfolded in the Pre-Republic era between the Gree Empire and the territories controlled by the Kwa. The basis of the Celestials was used in the construction of hypergates and Infinity Gates, which generated power surges that sparked disagreement between the Gree and the Kwa. This disagreement escalated into a millennia-long war that persisted until approximately 27,000 BBY, around the time the Devaronians and Gossams were experimenting with the tumble hyperdrive. Ultimately, the aggressively expanding Infinite Empire of the Rakata forced both species to retreat to their own territories, with the Kwa nearly exterminated. Centuries into the Gree-Kwa conflict, the dark side being known as Abeloth was released from her imprisonment by the Celestials for the first time, and she enjoyed watching the Gree parade three Kwa captives towards the Font of Power located on her prison planet.
