The stone ruins of Vatleria
During the time of the Galactic Civil War, the planet of Vatleria was home to some stone ruins. These ruins were utilized by Darth Vader as a base for the Imperial forces, and stormtroopers were stationed there to provide security. The location also included several traps. When the Alliance to Restore the Republic dispatched a unit known as the Rebel Four to attack the base, Vader sensed their presence using the Force and activated the traps. Consequently, all members of the Rebel Four perished.
