Flesh-rider

Flesh-riders are terrifying parasites that invade the corpses of men and control them in halting, jerking motions. A flesh-rider's proboscis is needle-sharp, and twitches constantly when it scents human prey. They are intelligent enough to speak, but usually produce only a high-pitched whine when excited by bloodlust.

The Apprentice encounters a swarm of flesh-riders in the Great Southern Wastes, amid the burned ruins of the witch Juliana's lodge, and later encounters a much larger swarm in the town of Eastpass.
