Cloud City/Legends

Cloud City is a mining colony on the planet Bespin. It receives its name from the fact that it floats high above the actual planet&mdash;an uninhabitable gas giant. The city's chief export is Tibanna gas, which is used in the production of weapons and hyperdrives. At the time of The Empire Strikes Back, Cloud City was run by Lando Calrissian, who had won administration of the city in a Sabacc tournament.

The Empire Strikes Back
It was here that Han Solo, Princess Leia and Chewbacca came after escaping the Imperial attack on Hoth; Han hoped that Lando's people would repair the Millennium Falcon ' s malfunctioning hyperdrive.

Unfortunately, Boba Fett had tracked the Falcon to Cloud City, and Darth Vader had already made a "deal" with Calrissian: in exchange for Calrissian's friends, the Empire would leave the small mining operation alone. To his credit, Lando hadn't actually been given any choice in the matter&mdash;Vader had made up his mind: this was all an elaborate ploy on his part; the primary goal: capture Luke Skywalker.

After capturing Luke's friends, Vader began torturing them. He didn't ask any questions, so this was most likely an attempt to gain Luke's attention&mdash;if, through the Force, he felt his friends suffering, surely he would come to rescue them.

This method worked: Luke prematurely left his training on Dagobah (promising Yoda that he would return) and traveled to Cloud City, where he engaged Darth Vader in a climactic duel. Vader attempted to turn Luke to the Dark Side, but was unsuccessful&mdash;even after cutting off Luke's saber-hand and then revealing that he was Luke's father.

Luke was not successful in the rescue of his friends; however, Lando did try to help Leia and Chewie rescue Han from Boba Fett. They were unsuccessful, but they did manage to escape themselves; they also rescued Luke from a weather vane as they escaped.
