Present the Vrykul Scroll of Ascension near the Thane's Pyre to call him out and slay him. Afterward, due to the nature of the ritual, you're sure that Father Levariol at Westguard Keep will be interested in seeing the scroll.
This huge scroll is made from dragon skin. Unfurling its more-than-ten-foot length, you can see that the images painted upon its scaly surface depict a mysterious vrykul ritual.
A vrykul thane, surrounded by angelic-looking beings, ascends into the heavens. A mysterious, darkened figure looms large in the picture's background.
A tingling in your gut tells you that the thane of Skorn is about to do this. You must stop it! A large pyre sits at the top of Skorn in front of the thane's lodge.
