I saw this book mentioned in a forum thread and picked it up on a whim. OMG this book is good! I mean, bacon-level good!

In a nutshell: it appears to be a book about fairy tale "tropes", but it basically describes an entire medieval fantasy world. I think any DM worth his salt should have this on his bookshelf.

That is all.
