We had the pleasure of interviewing Jeff Stevens and this amazing product on our podcast Crit Academy. Listen here. This product is a piece of golden art. The collection of villains are interesting, well developed and you're given options to introduce them not only as big bads, but also as quest givers or just information givers. Giving you great NPC's for your world with fleshed out backgrounds and some with maps for their lairs. A must have resource for any DM.
Great work Jeff!
