This is really good. Its not perfect, but its well worth your time and money if you want to play an OSR style exploration game. There is tons of content here you can chop it up or use it as a complete campaign. The art is good, the content is fun. There is enough detail here to run things out the box but not so much you can't jam on it in game. No long winded exposition or history of the 9 realms here, you will be up to your neck in skeletons right away. Lots of tables and charts and solid advice for reusability. I bought a ton of RPG modules over the years and 90% do not get the use that this one had gotten and I have only scratched the surface on it.
Super example of the genre.
