The secret sanctuary of Darth Vader, Bast Castle was an immense black fortress located near a beach on Vjun. His personal home, Vader often retired to Bast when not on assignment for the Emperor. Very few sentients knew of its existence and it was here in solitude that Vader studied the dark side and attempted to learn what he needed to heal his broken body. After the death of both Vader and the Emperor, the castle stood alone and forgotten for years.
