Large Cavern

The Large Cavern is one of the two Castlevania: Order of Ecclesia super-hard secret levels, along with the Training Hall. It looks a lot like Castlevania: Portrait of Ruin's Nest of Evil subterranean dungeon. It contains the game's hardest foes and an optional and hyper-violent boss, the Chinese Vampire Jiang Shi. The song Riddle plays in this stage.
