From publisher blurb:
The plan is for every Monster Menagerie to offer a set of monsters that match a theme, with full write-ups, simple index card style summaries for use at the game table, and printable standee figures for every monster.
Each volume in the Mythic Menagerie series presents a small set of monsters tied to a single theme, but spread over a range of CRs.
