Schnell Ruins is a dungeon in Wild Arms XF, where the rest of the fourth act of the story from Act 4-7 onwards takes place, as the location of a succession of consecutive battles towards the endgame. Located in the desert near Lefas Corner, the location is the ruins of a former capital of Elesius. Chevalet Blanc arrives here in search of fugitives Edna Warren and Charlton Blunt as well as missing princess Katrina Liane Elesius. They engage in battle with Charlton and his army of animated corpses until Eisen Brenton and the Royal Knights of Elesius arrive on the scene, chasing off Charlton and then engaging in battle with Chevalet Blanc, declaring themselves to be rebels who oppose the kingdom. Immediately after, the Zortroa Kinship attack, but Chevalet Blanc finally defeats them for good. They travel to an underground cave while searching for Charlton and Edna, and face the Tormenta Triad once again, where the triad perishes. Upon reaching the surface, Chevalet Blanc is also forced to fight Katrina Liane Elesius and the Guardian of Fear controlling her. Katrina disappears, and Charlton returns, luring the heroes to another underground location, this time a temple. Edna betrays Charlton by sabotaging his spellbook, leaving him to be killed by his own undead army as she makes off with the kingdom's stolen treasures.
