Fly towards the northeast continent, then land at the western tip. Continue the rather long trek southwest towards the temple on foot. Once there, talk to the sage. He'll tell you to sit on the throne, which is in the northwest room of this area. You'll find yourself on 2F now.

There are several warp points in this room. The first 2 should be pretty linear, then take the bottom one next. Keep going, and once you see 2 warps, take the south one. Go through the lone warp, then into the one directly ahead. At the next area, go east into the room containing the "GAUNTLETS". The treasure is guarded by Clay Golems.

Leave the room, taking the left path south through the warp up ahead. Go up the stairs to the next area. Just follow the path while picking up all the treasures you find along the way -- "HEALING STAFF", "STEEL GLOVES", "ICE BRAND", "RUBY ARMLET" "7,340 Gil", & "1,455 Gil". Pick up the "RAT'S TAIL", a key item at the end.

You'll be challenged by a Dragon Zombie, as soon as you try to approach the throne. Defeat the said enemy using higher level Fire & Dia spells. Head back to the Airship. Now go southwest, and you should notice that there are holes in some of the islands here. There are 6 of these, all of which lead to the Dragon Cave.

Go down every one to get a lot of treasures -- a large amount of gil, "TENT", "COTTAGE" & "GOLD NEEDLE". Once you're done looting everything, fly to the island with 2 holes, then go down the far right one. Head down to B2. Talk to Bahamut, and have him upgrade your character classes.
