A Decarnocimex is an immense cricket-like creature measuring anywhere from five to ten feet long. They have a heavily-plated exoskeleton, four crawling legs, and two bladed forearms. The overall coloration is greenish-brown.
Decarnocimex's were flesh-eating, oversized relatives of crickets, with bladed forelimbs for tearing apart carcasses. Aggressive hunters as well as scavengers, Decarnocimexes would attack small animals unfortunate enough to fall into their hellish domain, carving them up with their claws and razor-sharp mandibles.
