Nek

The Nek are an ancient race of underground-dwelling demons who were once angels. God sent his wraith upon several angels who commited each of the Seven Deadly Sins. He made their skins burn in the sun, and their eyes burn in the light. They were thrown upon Earth, and their Sun schorched their skin till it was burnt, and their eyes red from pain. They retreated to the underground, and only come up at night to feed. Their ever-burning hatred to God and all of mankind makes them dangerous foes, and very hard to kill. They will stop at nothing to destroy anything they can.
