The Lost Aqualish were a group of Aqualish warriors who had settled on Talus where they lived in isolation. Their ancestors originally relocated on Talus during the Aqualish–Republic War centuries prior to the Galactic Civil War, and eventually disappeared into oblivion. Due to their state of isolation, the Lost Aqualish had no knowledge of the ongoing Galactic Civil War between the Rebel Alliance and the Galactic Empire.
