I've been blogging a few years about medieval stuff in gaming, but I've been doing it in Swedish. Last year for Epimas I collected some of that material, translated it into English and expanded it. It's been on DriveThru a few weeks, and right now (24/1) it's Deal of the Day, so please do check it out!Monasteries and Relics
includes tables for creating a monastery, rolling what kind of relic it might have, an NPC seller of false relics and 20 character/adventure hooks. The whole thing is especially suited for historical/near-historical fantasy like Ars Magica or Pendragon.
