This page offers a guide on where to locate and how to complete The Anchoress, which is a Mystery located in Oxenefordscire.
Unlock the Church
The Church can be located north of Buckingham. The Church’s door is locked, but if you head around to the other side of the building, you’ll be able to shoot the lock through the barred window. You can then head inside of the church and make your way down into basement.
Within the basement, you’ll find the Anchoress, and upon talking to her you’ll discover that she hasn’t been outside in years. You’ll want to convince her to come up to the surface and see the world again, you can choose to use your charisma if you have Charisma Level 3.
When the Anchoress leaves the Church the mystery will be completed. If you head back down into the basement, you’ll be able to move the large moveable shelf on the left wall to reveal a chest full of silver and other supplies.
