Aginor created the Trollocs during the War of Power as soldiers for the Shadow. They are huge, maybe eight feet tall. They have the body of a man and the head and feet of an animal such as a bear, bird, wolf or goat. They are very strong, but they are too stupid, lazy and cowardly to be good soldiers.
Trollocs see well in the dark, but bright light blinds them. Some can track by scent or sound, but they are lazy and easily give up. They kill for the pleasure of killing. They cannot be trusted unless they are afraid of you, and then not far.
