From publisher blurb:
Terrors of the Ancient World is a collection of monsters to liven up your Dungeon World game. Inside this book you will find over a dozen new monsters, all of them illustrated in glorious full colour.
Each monster comes with some combination of adventure hooks, custom moves, traps, fronts and dangers, magical items, and even a couple of maps. Demons can be summoned and bargained with, gods can be worshipped in exchange for new spells and other special powers.
There is also a new base class, the Satyr, along with satyr race option moves for other classes.
