What is it mortal? Have you come to be of service to Sheogorath? That in of itself speaks towards your madness. This pleases me. Fetch the Fork of Horripilation from the Mad Hermit near Al Redaynia. Take care with him; he's not the most...stable man.
Use the fork wisely, mortal. Few have wielded it to have not come away unchanged. Use the fork to strike a death blow to the Giant Bull Netch that resides near the hermit. Do this, return the Fork of Horripilation to me, and Sheogorath will reward you well.
