Ki and Gil will enter this room through the door at the bottom-left of it. It contains twelve Black Vampires and eight Red Slimes (thirty-four hits to kill).
The key at the bottom of the room opens the aforementioned door at the bottom-left of the room, the key at the centre of the room opens the door at the left of the room, and the key at the top-left of the room opens the door at the top-left of the room. This is the largest-size room in the game so far.
The aforementioned door at the bottom-left of the room leads back to Small Dome (Room Pass: Q37), the door at the left of the room leads to Watch Tower (Room Pass: 9F2), and that door at the top-left of the room leads to Holy of Holies (Room Pass: H3Y). You should remember these Passes...
