Ki and Gil will enter this last normal room through that door at the top-right of it. It contains one Druid, one Sorcerer, one Wizard, eight Akynd Knights and three Land Urchins. This is the only room in the game containing Akynd Knights - and Gil will start out directly on top of one of them, so be quick.
The soft-light hologrammatical image of Ishtar herself, who at the top of the room, can again be walked through by Ki and Gil, as if she was not there.
The key at the centre of the room opens the aforementioned door at the top-right of the room (there may be no key for the door at the top of the room but if you use the Duo Dimension spell in this room to restart it then make Gil walk up to it, it will open. A lot of people are still not aware of this fact).
The aforementioned door at the top-right of the room leads back to Portcullis (Room Pass: HF7 - the same as Boudoir), and the door at the top of the room leads to Main Gate (Room Pass: 7C7 - same as Quox's Labyrinth, not that you'll actually need it anyway given that you already won the game).
