Ex:SWTOR 2, There is only Passion
The Kumumgah were a technologically-advanced species. They eventually developed spaceflight and, against the wishes of their elders, began the colonization of other worlds. This drew the attention of the Rakata, who conquered, enslaved, and annexed them to their Infinite Empire in 25,793 BBY. The Kumumgah eventually rebelled and were punished by the Rakata, who bombed the surface of their once lush world.
