A very good friend of yours recently became violently ill. She ranted and raved like a person possessed, which was the exact diagnosis that the head of the church and the local doctor arrived at. They said that there was nothing they could do: there is no medical cure and the wizards you have found so far have said that the problem was not their area of specialty.
However, you finally managed to find a wise old sage that told you of a powerful holy man that specialized in demonic possession. The man's name is Marron and he lives somewhere on Mount Sunis in the caves. They say he has lost his marbles and now lives in recluse with his strange friends.
You do not know whether you can get Marron to come into the village to help Katharyn, your friend, so you decide to take Katharyn up to the holy man, instead.
Katharyn is much too violent to take along so you must bind her and carry her. So, you chain her and wrap her in a canvas bag and head off for the caves of Mount Sunis.
