Burrower demons were a parasitic species of demon. Burrowers took temporary possession of human bodies, eviscerating and killing them in the process, jumping to a new host when the current one began to rot and break down. Talamour was one of these demons.
Burrower demons endowed their hosts with superhuman strength and reflexes. Additionally, these demons were able to sense and differentiate non-humans from humans, as Talamour demonstrated.
