After rescuing Hilda, speak to the king. Then go to Josef in Salamand. (He will join your
party!) Then go to the sumit cave and find the blue crystal on the first floor. Then Josef
will show you the secret door on your right. In there you will get a snow craft. Take the
snow craft to the snow plains. (Entrance is on left of Salamand.)Then traverse the snow
plain until you reach a cave. When you finally get the Godesses Bell. (Which is at the end
of the cave) Go to Kashuan keep. The Godesses Bell is the key to the locked door! Then go
through the keep to obtain a item that lets you cary the sunfire. Then go to the sunfire
and use the item you just obtained to get the sunfire.
