The Imperial hideout functioned as a base for a Galactic Empire squad after the Battle of Endor; it was originally an old observatory located on Narthex, the moon orbiting Catadra, a planet within the Cerberon system. In the course of the New Republic's campaign to seize Cerberon, this Imperial unit came into possession of Caern Adan, a New Republic Intelligence agent who had been abducted and then sold at an auction. Following Adan's trail, New Republic pilots Yrica Quell and Nath Tensent successfully freed Adan, with Quell killing every Imperial present in the observatory.
