Creatures that belong neither to the natural world nor to the magical Prim, described as misbegotten beings from somewhere between the two. The taheen have the bodies of men but the heads of various beasts - some resemble birds, others mammals. Unlike the can-toi, true taheen thoughts sound like white noise to psychics and cannot be progged or read. They look upon humans as an inferior race and serve the Crimson King as guards and administrators in End-World, particularly at the Devar-Toi.
