The Return of Ishtar/Druaga's Grave


 * Ki and Gil will enter this room through the door at its centre-right. It contains twelve Purple Vampires and four Orange Vampires (four hits to kill).
 * The grave after which this room is named is located on the left side of it (it is marked with the letters "R.I.P." and a silhouette of Druaga himself).
 * The key at the bottom of the room opens the door at the top-left of the room, the key at the right of the room opens the door at the top-right of the room, the key at the centre of the room opens the door at the bottom of the room and the key at the bottom-left of the room opens the previously mentioned door at the centre-right of the room. This is the first of many doors that will lead back to earlier, previously visited rooms in the game.
 * The door at the top-left of the room leads to Empty Gallery (Room Pass: DV9), the door at the top-right of the room leads to Banquet Area (Room Pass: 7CY), the door at the bottom of the room leads to Jewely Storage (Room Pass: 2F9) and the aforementioned door at the centre-right of the room leads back to Top of the Tower (Room Pass: 2C9). Again, you should remember these Room Passes (except for the last one, of course)...
