Detailed Walkthrough
A while after completing The Man Who Cried Wolf the Courier will approach you with a letter from Falk Firebeard asking you to return to him. When you get there he will inform you that since you stopped the ritual, you have a connection to Potema (the wolf queen) and that she did not get destroyed when you stopped the ritual, she just doesn't have a body. He will inform you of some tunnels underneath the chapel that should lead you to her.

When you arrive in the chapel, Styrr will ask you to bring her remains to him so he can bless them. In the tunnels you will arrive at a gate with no visible means of opening it. Potema will talk to you and then open the gate. Fight your way through draugr and vampires until you reach a room with a throne in it. Potema will attack you in her ghostly form and once you defeat her all you need to do is take her remains from the throne and take them to Styrr. Return to Falk afterwards for your reward.
