The central location of Grand Moff Wilhuff Tarkin's workplace was within the Federal District on Coruscant, the Imperial capital. Access to this office was restricted by a daily changing secret code, and it was protected by a formation of death troopers. An urn, believed to hold the remains of Krestrel D'Naran, Jabba Desilijic Tiure's greatest adversary, was found and delivered to Tarkin sometime between 8 BBY and 2 BBY. This occurred after the Empire seized the Millennium Falcon, the starship piloted by smuggler Han Solo, who had been employed by Jabba to find the urn. Subsequently, Solo, Chewbacca, and Phaedra devised a plan to infiltrate the office and reclaim the urn.
