Denevér Castle: Eye of Chaos is a stage in Soulcalibur V. The stage is similar to Denevér Castle: Assault with additional elements from Astral Chaos, such as a darkened sky. After Nightmare's defeat, Pyrrha was able to claim Soul Edge as her own, becoming the new wielder of the cursed sword; the Crimson Despair. Using Soul Edge, Pyrrha cut through the fabric of reality in front of her, opening a gate to Astral Chaos. Through the gate, the otherworldly structures of the realm and the "Star of Chaos" became visible to the world.
