Trolls are the top predators of the underworld.
Semi-mineral beasts, they are exceptionally hard to kill. The are large, averaging at about 10 feet tall, equally wide and walk with a simian gait. Long arms ending in rending claws give them a formidable killing power. Long, dirty hair adorn their heads and small beady eyes stare at a world that can only be understood as either "Edible" or "Inedible" to the small brain of a troll.
