The Angchu are one of the two tribes of Canthan Tengu (the other being the Sensali Tengu).
Unlike the Sensali tengu, the Angchu have made peace with humans after the end of the Tengu Wars. Even though many humans still look down on the Tengu as inferior creatures the Angchu cooperate with them.
The Angchu deeply hate the Yetis, their archenemies since before the time Cantha was united as a kingdom.
