Abbey of St. Markovia

From Adrian's 'Guide to Barovia':
An abbey in the northeast of Krezk. Led by the Abbot of Saint Markovia, a celestial. It used to be a place of healing and rest, in honor of one Saint Markovia. A goodly woman who used to heal the sick and ailing.
Now it is filled with monstrosities stitched and put together by the great Abbot. The people of Krezk don't seem to be aware of what's inside this place and avoid it. A good thing too because this place is like a child's nightmare of a zoo mixed in with a good dose of creepy infirmary. Spider ladies, donkey men and two headed baby crabs all around.
The only reason you should even think of going there is if the Abbot is still around and you're willing to risk your life for a divine favor or two but these do not come cheap. You know what, just avoid the place all right?
If you do happen to go there, make sure to keep a wide berth from any chained up 'patients'. Don't be around any of them during feeding time that is indicated by the ringing of the bell from the tower.
