Chaos is the name given to the mysterious entity who rules the Chaotic Realm: a demonic and warped dimensional plane where negative energy and human malevolence gathers, which only Dracula or his reincarnation can enter. The Chaotic Realm is likely the place from where Count Dracula and the Castlevania emerge when resurrected, given that it contains an amalgamation of all parts of the Castle. It might also be linked to Hell and the Demonic Planes where the demons and monsters come from, as it spawns many monsters.
