This book is an excellent companion for Ithura & Porthaven (A medieval Barony and Port Town), The Marketplace (realistic prices for medieval goods and services), and, of course, Orbis Mundi 2 which covers the nitty gritty of the medieval period as it actually was ... completely different from the hollywoodised pastiche that is the 'background' of pretty much all FRPGs.
