I cannot describe the hangar only because the only characters who have seen it fully are Kolgol n his squire and Olav of Unen.
Therefore if neither of those two players choose to describe it other characters really won’t have any operational information on the hangar beyond the following
-
was built into a cliff face somewhere along the coast of Bartsport
-
had some unknown method of connecting the hangar to the manor house, unknown method used to connect elevator to manorhouse. ( elevator Shafts don’t line up geographically)
