What is required for a monastary

[Jacktannery]

... and possibly a herd of cows for vellum.

They are going to need a bull too if they intend to make their own vellum! They would also require a good source of freshwater (ie a river) to fill and wash out the tanning pits for steeping the calf hides (& cow hides for the leather bindings). The cow- and calf-bones would then be turned into bone pins, bone combs, and other bone objects, and perhaps hooves into glue.

Jack,
Fresh flowing water would almost be impossible (nowhere above the mountain for it to flow to), That is why the cisterns, to catch all rain off the mountain.

Meshon,
Thanks for the tip about cottage industry. That would be needed, if for nothing else, to buy ore for the smelter. I also was considering sheep or perhaps goats instead of cows, they seem to be more hardy.
