the white mask is in fynn. talk to the princess and gordon for these key words. :Ekmet Teloess, mask, ultima tome, and mysidia. then go into town and go north west then west and south and go into that door and ask that guy Ekmet Teloess. then go back into castle fynn and go into the topright hand corner where hilda and gordon are then face the east wall and press A. then hit terms and use Ekmet Teloess. this can help too.

Hmm... This place is a nice drawback to your quest... the enemies are a bit
out-dated so it should be facile. However, the items are spaced apart so you
might have to fight quite more than a few monsters in six open-ended floors.
As a prelude to this dungeon, Square has presented you with three downright
PATHETIC items: a Shirt, a Knife and Eye Drops. Fun! The KNIFE is stabbed in
the southeast, EYE DROPS to the northeast, and SHIRT draped on the heart of
the floor. Done with them all? Northwest... you know what to do.
God, what a joke. The items are still pathetic. We aren't sex slaves, you
know, Square! We need good ones! An ETHER is in the same circular hallway as
the one you entered from B1F, and there's one more POTION in the southwestern
corner. The northwestern one has a MAIDEN'S KISS. The last corner, the
northeast? Yeah, the stairway to heaven.
Yet another corner-based maze. I'll make it quick, so I won't bore you out.
Southeast=HI-POTION. Southwest=FLAME SHIELD. Northwest=SPIDER'S WEB, and a
few steps below that chest has the stairs.
A bit more complex than just a chest-in-every-corner theory. In the first
fork, head to the right first to find a GUARDED chest with a POWER STAFF
inside. Now, a blood sword can suck the enemy's HP and make it yours but it
has ridiculously low HP so I guess it's worthless but keep it for now, don't
sell it some merchant. Go to the central point of the room and head northeast
for a FLAME ARMOR. Southeast is the exit, but don't forget the BETRAYAL FANG by
the stairs. (God, how can I say 'stairs' differently? So repetitive)
Getting closer to the waterways, as evident by the floods in this floor. Wade
through the waters to the third hallway to the right. On that hallway, there's
a chest guarded by a new monster: Rhyos. He has 750 HP so be extremely careful
fighting him. The reward? Worth it! It's an ORICHALCUM, one of the best
daggers in the entire game, if not the best. Now, there's no stairs this time.
Instead, you have to find the right door. There are several doors here...
which one's the right one? Go to the northeastern passage and enter the second
door from the right.
Grab the ultimate treasure, the WHITE MASK and go further north and step into
the portal to complete this quest!
