The large cavern is an optional area that is unlocked by going through the secret exit in the Underground Labyrinth in Dracula's Castle. It contains a series of rooms that lead to the boss. Each room can be cleared either by defeating all enemies or after a set amount of time has elapsed. Between every two rooms is a vertical room with no enemies, but they contains chests. The Globus glyph can be absorbed from Demon Lords.

Boss: Jiang Shi
Once defeated, Jiang Shi will be sealed. You can attack the seal to release him and fight him again. This can be repeated indefinitely making this area an effective place to level up. Defeating Jiang Shi also satisfies Irina's third quest, An Unwelcome Guest. The very last room is a warp room that will take you back next to the entrance.
