Book of Beasts: Monsters of the River Nations
This bestiary presents 25 monsters associated with the River Nations and its plains, forests, freshwater environments, and mountains. Low-level creatures include semi-aquatic animals and dangerous plants, while higher-level encounters feature playful fey, tormented undead, and a small number of extraplanar beings. The book also introduces the armouchi, a playable primitive humanoid race of uncertain origin. Strong and widely looked down upon by other peoples, the armouchi can find a place among civilized communities.
