The Sice system represented a star system that held within it the planet called Sicemon. This grassy planet served as the location of a Rebel Alliance base.
Originally, the Sice system was featured in an early version of the script for Star Wars: Episode VI Return of the Jedi. In this draft, the Millennium Falcon journeyed there after the rescue of Han Solo, intending to meet up with the Rebel Alliance at their Sicemon base. Despite this initial plan, the system and its planet were ultimately omitted from the final cut of the movie. Instead, the Falcon met up with the Alliance Fleet close to Sullust.
