The Return of Ishtar/Shunned Cavern


 * 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...
