Well, this is going to be darned useful. Full of random charts using 30 sided dice (yes, with some options if you don't have one). Adventure generator tables, weather tables based on climate, temple generators, cult generators and more. It also has a couple worksheets I'm very excited to try out. The Hex Crawl Worksheet, which has a large hex & many smaller ones nested inside. This lets you do hex maps at various scales, so you can really drill down from the "atlas" scale to the "local area" scale with some consistency. This book is going right into my piles of GM resources. I believe you can get the PDF on DriveThru, but I got the it print on demand on Lulu.
