Ki and Gil will enter this room through the door at the top-left of it. It contains one Druid, eight Black Bats, and eight Black Lizardmen (602 hits to kill).
The key at the bottom-left of the room opens up the door at the top-right of the room, and the key at the bottom-centre-right of the room opens up the aforementioned door at the top-left of the room. None of the other five keys that are located at the top-left, top-centre-left, top-right, bottom-centre-left and bottom-right of the room open any of the doors in the room, which means that there is no key for the door at the top of the room. Remember this.
The aforementioned door at the top-left of the room leads back to Command Post (Room Pass: HC9, same as Knight's Chamber), and the door up at the top-right of the room leads to Barrel Vault (Room Pass: D39 same as Priest's Quarter). You should remember the second of these Room Passes.
