Wunderweltraum is a dungeon in Wild Arms 4 following Aerial Fortress Eulalia and preceding the Sea of Trees. This level becomes inaccessible and can not be found on the world map. The player party does battle with Belial twice here, after the death of Scythe Riebaure causes her to go berserk and create a pocket dimension to torment Jude's party. The BGM that plays here is Nightmare Spiral (Disc 2, Track 6).
