Shadow trolls, also known as deep trolls and dark trolls, inhabit the dark recesses of the Underearth, never venturing onto the surface world except at night or on days when the sun is blocked by dense, heavy clouds. On the latter, they wrap themselves in shadows to prevent exposure to the weak sunlight and rarely tarry, for any exposure to sunlight can be fatal. Those unable to return to the safety of the Underearth while the sun shines, risk being turned to stone.
Shadow trolls are small and wiry with midnight black skin and feral, yellow eyes. Their preferred tactic is to concentrate on a single victim and rip it to shreds. They dine primarily on small animals, but will devour anything they can kill.
