Dralth

The Dralth are about as simple as a creature can possibly be and still be a functional engine of death, destruction, and chaos. Possessed of average instincts but barely enough intellect to have a theory of other minds, the Dralth are used as assault and seige engines in Demonic Hosts, or dispatched to the Prime Material Plane singly or in small groups to smite individuals or communities that have incurred the wrath of a demon powerful enough to command them.

Laying waste with their impossibly huge maces and blade arms, protected by layers of natural armor and Abyssal steel, a Dralth is the perfect annihilator: stupefyingly powerful, utterly remorseless, and driven most by a desire to take things apart as violently as possible.
