Tremor Base, also known as Imperial Outpost RD778083, was an Imperial Outpost established on Otavon 12 during the early years of the New Order. It was used as an AT-AT production facility.
During its existence, it was continually harassed by Ovoni rebels, who later succeeded in destroying it thanks to the sacrifice of Jedi Master Hylon. General Crik of the Imperial Army was the commanding officer of the base.
