The Ghost Wookiee was said to be an angry Wookiee ghost who lived on the planet Kashyyyk and attacked travelers. In 196 BBY, while on a field trip to Kashyyyk, Egon told several other padawans about this story, which caused them to run away from their camp after mistaking the Jedi Kitmum for the Ghost Wookiee.
The Ghost Wookiee was first mentioned in the 2013 novel Jedi Academy written by Jeffrey Brown.
