Cassidode VI rebel outpost

At some point prior to the Battle of Scarif in 1 BBY, Monsbee was transferred to Blue Squadron on the moon Yavin 4. His time on Cassidode VI meant he had logged more solo flight hours than anyone in his new squadron, with the long periods of isolation resulting in Monsbee becoming chatty in the recreation room.

The outpost was first mentioned in the 2016 reference book Star Wars: Rogue One: The Ultimate Visual Guide, which was written by Pablo Hidalgo.
