Cloud City is a fictional floating city on Bespin, a planet in the Star Wars universe which appears in the film The Empire Strikes Back. The city floats among the clouds and is home to Lando Calrissian and his bionic assistant, Lobot. It is a mining colony used to mine Tibanna gas , which is used for weapons and hyperdrives.
The city is patroled by cloud cars, which escorted the Millennium Falcon on its entrance to Bespin.
Cloud City is the largest of the airborne Tibanna refineries, and it is also unique, doubling as a top-notch vacation resort and entertainment complex.
In the bowels of the station, Tibanna is frozen into carbonite blocks for transport, and in the uppermost towers, idle tourists win and lose fortunes in the Royal, Trest, and Pair'O'Dice casinos.
The city is the setting for the famous line in The Empire Strikes Back in which Darth Vader informs Luke Skywalker that he is Luke's father, which was something Obi-Wan Kenobi had neglected to tell young Skywalker.
