Daemonic Device [BARomero's nameless challenge]
Skulking in the corner of the room, it waits. Its appetite for the living is insatiable, implacable, immense.
A faint smell of ozone surrounds it, and its bright red cover regularly resonates with repulsive squelches. Its appendages are caked with the detritus of the slaughter that occurs week after week.
Turn it over and, if you are careful enough not to get caught, you can look into the business end of this singularly ravenous device. Sharp edges and a maelstrom, caged violence incarnate. Further leavings splattered all over the inside, hardening now into a repulsive crust.
Who is in control of this beast? It certainly never does as it is told.
