You are looking for crystals around in Stormterror's lair and it's quite hard since there's a lot of wind and it's dark.

Then you see a tall man with wings flying towards you and he lands in front of you. His wings fold back and disappear.

"Who are you? What are you doing here?! This place is sealed."

He spoke in a low and deep tone, he looks familiar. Is he Dvalin? If he is, then why does he looks human and not a dragon anymore?
