Day to day life of these Monastic Orders? Makes sense and highly variable. Some would be strict and authoritarian and others more collective. Vows of silence or roaring drunken sing alongs nightly. I should through in Nuns and Nunnery's or Sororities to keep it rounded.
Maps of the Order house or Chapter houses? There is alot of the actual places on the web. These are suitable as is or adaptable to post apocalyptic with re-purposed salvage. Maps of the Counties or holdings these are found in? The game book itself has some useful maps of Michigan, and the U.S. to get a GM started.
Day to day life will depend upon the Order, the function of that Order, and ones plaxe in the pecking order. An order raised to be hospitalizer would function as rest stops for travelers and for medical care or similar aid. Another Order may be raised to rid the land of the massive scourge of enormous carnivorous boars eating the people and destroying farmland.
As a player, a hospitaler, has advanced beyond a novice with a mission to heal the sick and comfort the dying. Sent on a circuit of villages to preach and heal; or sent with a Militant Order as their battle medico.
