In 4 ABY, an agent of the Rebel Alliance attempted to aid Doc Shemza, a scientist, on Bespin's Cloud City. Shemza was abducted by thugs, but eventually rescued by a group of vacationing former-students from Naboo's Royal House of Learning. Shemza, accompanied by the Rebel agent's droid, Shorty, and the vacationing students, lead the way to Landing Platform 21. Along the way, the Galactic Empire attempted to occupy the planet. Shemza's contact flew the group to safety.
