Ki and Gil will enter this room through the door at the bottom-left of it. It contains six Blue Captain Knights (with green eyes), and four Mirror Knights.
The key at the left of the room opens the aforementioned door at the bottom-left of the room, and the key at the top-right of the room opens the door at the right of the room. The aforementioned door at the bottom-left leads back to a previously visited game room, while the one at the right does not.
The aforementioned door at the bottom-left of the room leads back to Training Yard (Room Pass: 937) - and the door at the right of the room, like the one at the top-right of Undead Graveyard (and the one at the bottom-right of Knight's Chamber), leads to Junction (Room Pass: QCY). Remember it.
