Siege of Castle Karstaag

I have been sent another dream by the Daedra Lord Hircine. He has told me that Castle Karstaag, at the north shore of the island, is under siege by renegade servants. The owner of the castle is important to him, and Hircine would like me to enter the castle and kill the rebellious creatures.

I have entered Castle Karstaag and spoken to a Riekling named Dulk. He tells me that another Riekling named Krish has enlisted the help of grahl to attempt to take control of the castle. I should enter the caverns below the castle and destroy the grahl and the Riekling Krish.

I have killed all of the grahl and the Riekling Krish. Hircine will be pleased.

Hircine was pleased with my efforts, and has rewarded me with Hunter's Wind, the ability to completely restore my health once each day.
