Celesti Ruins is a dungeon in Wild Arms 4 that lies northeast of Port Rosalia. It is during this level that further exposition is given of the history of this game's version of Filgaia, specifically the war that transpired over a decade prior to the events of the game. Storywise, Celesti Ruins happens to have been a town that fell victim to that war. The majority of random encounters will be with Undead monsters, and the Earthbound Spirit is the first of two bosses the player fights. This dungeon is where the player party has its first encounter and battle with Jeremy Non on its way to the White Orphanage. The BGM that plays throughout this dungeon is Shadow Territory.
