A set of stone ruins was located on the planet Vatleria during the Galactic Civil War. Darth Vader used the ruins as an Imperial base, and stormtroopers guarded the location. A set of traps was located on the premises as well. When the Alliance to Restore the Republic unit known as the Rebel Four attacked the base, Vader detected them with the Force and sprung the traps. The Rebel Four all perished as a result.
