Go back to Kazus where you'll find the Curse has been lifted (That means you can now buy stuff there!) after a short cut scene Refia leaves your party for a very short while. After the scene go to the Inn and speak to Cid who wants to go back to Canaan. You have to use the Airship to bring him home, so conquer the River with the Folding Canoe you received from the King to get the Airship back.

Fly back to Kazus and Walk into the House above the Inn (Takka's house), Cid will ask Takka to fit the Airship with a Mythril Ram to bust the Boulders which block the passage to Canaan. Exit the village and enter the airship. You will then meet Refia there again to join your Party.

Mythril Mines

Mythril Mines Item Checklist:
Equips 2x Mythril Swords

With Refia back in your party enter the mines North-east of Takka's house. Go into the main room and check the Northwest Pillar to open a secret passage. Enter it and follow the path to two chests (2 Mythril Swords). Exit the mine and fly West to the large rock blocking the path between two mountains. During a Cutscene the rock and the airship will be destroyed. Walk Southeast to the village of Canaan and enter it.

After a short cutscene Cid will leave the party and tell you to meet King Argus in order to make a new Airship. You can continue along the quest, but fist lets grab some loot!

Go to the house connected to the Inn and search the firewood beside the stove (Mallet). Go left of the firewood through a hidden passage below the lamp and search the pot (Golden Needle). Talk to the girl on the bed and Luneth and Refia will then decide to find Desch for her.

In the northeast part of the village is a pond, take the stairs in the north and follow the river to the west until you find a chest (Elixer)You'll need this soon. Head to the armory and buy anything you may need, then head to Cid's house north of the armory. Enter and talk to Cid, then Mrs. Cid. Use the Elixer on Mrs. Cid, and Cid will tell you about a secret path in his house!

Activate the lamp just above the bed and head through the passage, down the stairs. Grab the 8 chests (Phoenix Down, Blind, Golden Needle, 20x Iron Arrows, Great Bow, 2x Gnomish Breads and Potion). Walk down into the water and onto the small island in the southeast corner. Continue east, into the passageway and loot the chests (4000 Gil and 2x Phoenix Downs)

Buy anything else you need, exit the village, SAVE and walk east to the mountain, Dragon's Peak.

Dragon's Peak

Dragon's Peak Item Checklist:
Items Phoenix Down Gold Needle Spells Aero Mini(post-boss)

Follow the path up the mountain to the crossroads, take the southern trail for a chest (Phoenix Down) then continue up the mountain. When you come to another crossroads, take the one to the east for a chest (Aero) then return to the crossroad and take the path west. Grab the chest (Gold Needle) and then go up. Bahamut will show up and throw you into its nest. Once there, talk with Desch and Bahamut will show up again and try to fight you.

BOSS: Bahamut

NES version

In pre-islamic Arab culture, the Bahamut is a huge, powerful and benevolent creature that supports the World on its back. Later, Christian influence turned it into a "pagan devil", Behemoth (other devils: Astaroth was the Babylonian goddess of love Ishtar; Beelzebub was the Phoenician god Baal-Zebub, i.e. "Baal the Almighty").

You are far too weak to defeat him, so just run away.

After doing so, Desch will give you the Spell Mini and join the party. You will then jump off the mountain end up in a new area on the world map.
