Reports of Emerald Fist forces fighting alongside the forces of chaos rarely involve tales of full scale daemonic incursion; for tales of this magnitude do not leave the sanity of the few survivors to whisper them. Far more common are descriptions of strange mechanical beasts flying support or walking among the Fists. Of particular note are the flying constructs known as blight drones. These foul machines can be heard approaching with a sound akin to a swarm of flies. A large mass of flesh protected by thick armour plating is held aloft by two rotors. Whether this merger of armour and flesh is spawned directly from the warp or hammered into existance by Emerald Fists' warp smiths aboard their fleet vessels is unknown. A popular suspision among the Ordo Malleus is that of fatally wounded marines giving themselves fully to the corruption of the warp and becoming engorged with unknown plagues; destined to live on and spread rot and suffering from their bloated selves.
