The convent was established 300 years ago and is a walled estate of pastures, fields and barns. They produce enough food that they give aid to the refugees displaced by John Farson. Of late, the Big Sister of the order has decided the Sisters should spent one quarter of each year tending to those injured by John Farson; their white tents are a common sight on battlefields. The building is surrounded by the "stone-guardians", each representing a different animal from the Beams. These guardians adorn the tops of each of the twelve entrances into the convent which all lead to the central tower where the Sisters worship what is supposed to act as a symbol of the Dark Tower.
