Umpox is an imp who served the Sewn Sisters.
He traveled with the evil clones of the Wafflecrew while they rampaged through Port Nyanzaru and carried the eye the hags used to monitor them.  Umpox had a habit of transforming into different animals. He usually took the form of a rat when perched on Evil Strix, a spider when perched on Evil Diath, and a raven when perched on Evil Paultin. Umpox tried to stabilize the dying Evil Strix multiple times, to little success.
