Ilum system
Darth Vader: "Have you intercepted any information about our traitor?"
Stormtrooper: "We have cracked encoded transmissions which were redirected several times, but eventually routed to the Ilum system."
Vader: "The pirates' den, no doubt. Send a probe droid to confirm this…infestation."
