Kwi
this species of large, blue-skinned lizard was native to the planet Dathomir. The Kwi were believed to have descended from the Kwa, and elder species of sentient lives which developed the unusual technology known as Infinite Gates. During the last decades of the Old Republic, the Witches of Dathomir discovered the link between the Infinite Gate on the planet and the Kwa. They kept a small population of Kwi captive, and cut off their forelimbs for use in operating the Star Chamber which protected the gate. In order to the reptiles, the Witches implanted electrodes in their brains as a kind of fail-safe, in case the Kwi ever revolted. Decades later, it was learned that a rogue group of Geonosian bio-engineers were mutating Kwis to create Force-sensitive monsters, then providing them as minions to the Sith.
