Magori are crab-like creatures that know only hate and live to destroy sentient life. 

A magori looks like an ogre-sized humanoid crustacean with a reddish-orange carapace. It is capable of using tools and weapons crafted specifically for use with its crab- like claws and bizarre physiognomy.

Little is known about how the asexual magori spread their numbers, though a popular theory is that once every five years, all adults return to the sea and release an egg sac that will eventually give life to five exact duplicates of the creature in question.

The magori were originally under the guidance of another creation of Chaos known as the Coil, who magically augmented the duration of their obscuring mist ability and caused it to carry the disease known as Coil Cough. The magori have since scattered and make their own wayward paths throughout the world.
