The sorcereress Zandora is a good friend of the Dungeons Master who was banished into another world by Venger. She owns a chest that when opened in specific locations at specific times leads to other dimensions. Using this trunk the heroes rescue her with the help of map by opening it under the noon shadow of Skull Mountain which releases her from the dimension she was trapped in.
In the original script Presto asks whether she is a relation to Pandora. Dungeon Master replies, perhaps jokingly, that she is third cousin on Zeus's side of the family.
