Ki and Gil will either enter this room through the door at the centre-right of it (if they came from Observatory) - or that one at the top-right of it (if they came from Food Storage). It contains four Orange Vampires, four Green Vampires, four Black Slimes and one Blue Captain Knight (the green eyes).
The Treasure Chest in the wall's hole at the top-left of the room will cause the enemy characters to flicker (if any part of them is obscured by a wall).
The key at the top-left of the room opens the door at the bottom-left of the room, the key at the bottom-left of the room opens the door at the top-left of the room, the key at the bottom of the room opens up that aforementioned door at the top-right of the room, and the key at the bottom-right of the room opens that aforementioned door at the centre-right of the room. This is the first room in the game that can be accessed from two other rooms.
The door at the bottom-left of the room leads to Empty Cistern (Room Pass: H32), the door at the top-left of the room leads to Solarium (Room Pass: QC9), while the aforementioned door at the top-right of the room leads back to Food Storage (Room Pass: YF9), and the aforementioned door at the centre-right of the room leads back to Observatory (Room Pass: YC9). You should only remember the first and second of these four Room Passes...
