The Return of Ishtar/Common Room


 * Ki and Gil will enter this room through either that first door at the top of it (if they'd came from Guest Chamber), or the seventh one at the top of it (if they had came from Chariot Hanger). It contains one Wizard and sixteen "Blue" Super Ropers (which are yellow and take 1026 hits to kill; it is a lot).
 * The fifth key at the bottom of the room opens that aforementioned seventh door at the top of the room, the sixth key at the bottom of the room opens the eighth door at the top of the room and the seventh key at bottom of the room opens the aforementioned first door at the top of the room. None of the other five keys at the bottom of the room open any of the doors at the top of the room - meaning that there are no keys for doors 2, 3, 4, 5, and 6.
 * The aforementioned seventh door at the top of the room leads back to Chariot Hanger (Room Pass: 7V2 - same as Thief's Hideout), the eighth door at the top of the room leads off to Waiting Room (Room Pass: 9V7 - same as Alchemist's Room), and that aforementioned first door at the top of the room leads back to Guest Chamber (Room Pass: 737, same as Forgotten Room). You should remember the second of these Room Passes for later.
