Castle Zombie was built by Jonathan and his zombies north of where Castle Roogna would be built. He lived there when Dor traveled to the past to find a way to restore a zombie to life. After Jonathan died and became a zombie at Castle Roogna, this castle was abandoned. Humfrey rediscovered the castle while studying at the Demon University. When he married Rose, they moved into the castle and made it theirs. The original Castle Zombie is now the Good Magician's Castle.
