Ki and Gil will enter this room through the third door at the top of it. It contains twelve Blue Knights (which take thirteen hits to kill and have red eyes).
The hologrammatical image of the White Sword, which originally appeared on the fifth floor, can be walked through by Ki and Gil as if it wasn't there.
The key at the bottom-left of the room opens the aforementioned third door at the top of the room, and the key at the bottom-right of the room opens the fifth door at the top of the room. The keys at the left and right of the room do not open any of the five doors at the top of the room, so remember.
The aforementioned third door at the top of the room leads back to Armory (Room Pass: H32 - same as Empty Cistern), and the fifth door at the top of the room, like the one at the top-right of Armory, leads to Helm Storage (Room Pass: 9F2 - same as Watch Tower). You should remember these.
