Corvax Fen

One of Mustafar’s few vaguely hospitable places, the Corvax Fen is a bog studded with bleak irontrees, close to the splintered ruins of Darth Vader’s castle. The fen is guarded by a band of cultists devoted to Vader. Amid its swamps, Kylo Ren claims a Sith wayfinder that belonged to his grandfather.
