Forgefiends

A Forgefiend is a Daemon Engine used by the Chaos Space Marine Traitor Legions and the forces of the Dark Mechanicum. The Forgefiend was devised by Dark Mechanicum Warpsmiths to sow death and destruction amongst enemy forces from afar. The Forgefiend is roughly centauroid in form and stands on four powerful legs. The daemonic beast’s two arms are replaced with twin weapon-mounts that carry hell-forged parodies of Imperial armaments. When a Daemon Engine is forged in the citadels of the Warp, part of the fire that burns there is transferred into the heart of the engine itself.
