It seem GC ate my previous commentary, so let me try this again:
An exhaustive amount of information and very in depth plot that is quite memorable; I particularly like the link backs in the intro to other subs, it makes for a convenient reference for the reader.
However I do find the amount of depth here to be a little rigid and difficult to easily work into an already established campaign setting without it feeling like it was shoehorned in somewhat.
Adding in an additional section with plot hooks and adventure concepts, as well as some suggestions on how to include this faith/legend into an existing fantasy world would complete the piece for me, and give it that last bit of "ready to use" feeling it seems to lack for me.
Perfect amount of detail to make it wonderfully immersive and useable! Just enough back story for each location/NPC to allow you to spin a story when they meet the folks and get the players right into the city.
