“Burrower” is the nickname for a small blackmarket device used to cause irreparable damage to and eventually kill the intended victim.

Its lightweight metal housing contains self-powered rotors which propel the machine through skin and bone until it breaks out the opposite side. The rotors reverse and the burrower tunnels back through a victim’s body at a different angle, causing maximum damage. Retractable metal teeth that line the metal housing of the burrower make it difficult to extract while it is operating without further injuring the victim.

It is recommended to remove a burrower immediately upon contact before lasting damage occurs.
