Mutens are a type of dark creature in the Four Lands. They are described as large, lumpy, black, and Troll-like in shape. It is known that they lack feelings and first appeared as servants to the Warlock Lord. In Tanequil, Kermadec, Maturen of the Trolls of Taupo Rough, states that they are the Trolls' worst enemy. Mutens were conjured back into the world as servants of the Mord Wraiths and then again as servants of the mutinous Druids, led by Shadea a'Ru.
