Corstris
Corstris, situated in the Outer Rim's Quelii sector, was a planet abundant with forests.
History
Prior to the Battle of Yavin, Imperial Intelligence had reason to believe that Corstris housed a concealed base belonging to the Rebel Alliance.
Han Solo's time spent on Corstris did nothing to improve his feelings towards planets covered in trees.
Behind the scenes
The video game Star Wars: Rebellion for PC mistakenly locates Corstris within the "Quelli sector," an incorrect spelling of the actual Quelii sector.
