Ki and Gil will enter this room through the first door at the top of it. It contains two Sorcerers, two Wizards and eight Brown Lizardmen (take 802 hits).
The key at the top-right of the room opens that aforementioned first door at the top of the room - and the key at the bottom-left of the room opens the second door at the top of the room. Neither of the other two keys in the room do, meaning they are only there to confuse the room's first-time visitors.
The aforementioned first door at the top of the room leads back to Common Room (Room Pass: SF7 - it same as Trap Door Room), and the second door at the top of the room leads to Portcullis (Room Pass: HF7 - it same as Boudoir). You should remember the second of these two Room Passes.
