The Realm of the Mighty is the final "story mode" dungeon in IX. The Palace of the Mighty is located on the top of it. It is an evil transformed version of the Realm of the Almighty. The Realm of the Mighty can be returned to after finishing the story mode of Dragon Quest IX. One must go to the Realm of the Almighty and speak with Celestria; she will then be able to transport the player to the dungeon.
