The Miscellania and Etceteria Dungeon is a dungeon that runs underneath Miscellania and Etceteria. It can be accessed during and after the Royal Trouble quest. It is accessed via the dungeon entrances on either island. The Miscellania entrance is closest to the subterranean village, while the Etceteria entrance is closest to the sea snakes. A chamber to the Giant Sea Snake is close to the Etceteria exit; however, this cannot be accessed once the Giant Sea Snake is defeated.
