The Return of Ishtar/Calvary Prison


 * Ki and Gil will enter this room through the door at the top-left of it. It contains a total of four Pink Sword (Lizardman?) Knights and eight Black Snakes.
 * The key at the top of the room does not open up either of the two doors in the room - and the key at the bottom of the room opens up that door at the top-right of the room. There is no key for that aforementioned door at the top-left of the room, given that you reached it by using the Blue Crystal Rod spell on Masanobu Endō to make him wake up. The door at top-right of the room leads to Maze Passage (Room Pass: 732 - same as Dining Room).
