Cloud City was a city located on the gas planet Bespin in the Star Wars series. The city was a mining colony for TIbanna gas, and featured multiple carbon-freezing chambers to help preserve the gas. Cloud City was run by Lando Calrissian, its Baron Administrator, who won it through gambling. Hoping to seek refuge from the Empire in Cloud City, Han Solo, an old friend of Calrissian's, arrived with his friends. Solo was betrayed by Calrissian, and frozen in carbonite in one of the city's chambers by order of Darth Vader, who had, in Lando's words, "gotten there first." Solo was taken off of the planet by bounty hunter Boba Fett.
