Gamorr was the agrarian homeworld of the Gamorreans. It was a world constantly embroiled in clan warfare. Gamorrean clans fought for possession of the various troughs and mud fields that dotted the landscape.
Gamorr was first visited by the early Jedi and Sith. The native Gamorreans were inspired by the travelers from space... they envisioned a whole galaxy filled with mud and silage that they could claim as their own. So they took to the stars, hiring out as mercenaries, guards, and garbage disposal units. Those Gamorreans who remained on their homeworld continued fighting among themselves.
