Prince Xizor

Species: Falleen
Current Location: Deceased
Xizor (pronounced "shee-zor") was a Falleen Prince of House Sizhran and the Underlord of the powerful criminal organisation Black Sun during the Galactic Civil War. He was a ruthless competitor and charismatic public figure in high society with his headquarters in the city planet Coruscant. Close to the Imperial Palace, but less splendid, was Xizor's Palace: his home outside Falleen and a testimony of his status.
Following the Battle of Hoth, Prince Xizor was considered one of the most influential beings in the galaxy, on a par with both Emperor Palpatine and Supreme Commander Darth Vader, due to his exceptional wealth and influence through his criminal activities. The Dark Prince also maintained an amenable business relationship with the Galactic Empire.
The Falleen Prince took a great deal of interest in dealing with the Hutts; knowing that they were the masters of all illegal activities in the Outer Rim, he hoped to ally himself with them and expand his own power to even greater levels.
During the action referred to as "Shadows of the Empire", Prince Xizor sought to have Luke Skywalker killed in order to lower Darth Vader's standing in the eyes of Emperor Palpatine. At the Mos Espa Race on Tatooine Xizor Transport Company had provided several large luxury sand barges from which spectators could watch the race. By doing so, Xizor hoped to lure Luke Skywalker onto his barge, where the bounty hunter Skahtul could lay a trap for him. However, the plan went awry and Xizor had to flee to his skyhook. During a communication with his skyhook, Prince Xizor made the fundamental error of muttering Skywalker's name in his instructions to destroy a YT-1300 light freighter despite being warned by Lord Vader not to go after him. At that point, Vader gave the order to destroy the skyhook.
With the destruction of the skyhook, Xizor was presumed dead and his niece Savan took control of Black Sun, which consequently underwent a civil war and spawned at least one offshoot, the Black Nebula.
