Gamut Key possessed a dwelling situated in a small town located on the world of Kaller. Throughout the Kaller Invasion, the Devaronian Commander Kleeve, along with his Separatist Alliance troops, seized control of the estate while fighting against Jedi Master Depa Billaba and her military unit. Following the withdrawal of Kleeve's soldiers, Billaba chose to keep her troops from taking over the estate, opting instead to have them set up camp in the surrounding area.
