Pûkel creatures

Pûkel-creatures are animated stone or metal monsters magically instilled with enchanted spirits. Most are creations of the Drúadan, or "Wose," culture. Others are the work of the Daen Coentis, a proto-Dunlending people of the White Mountains among whom the Woses lived and worked. Realizing the value of these stone guardians, Sauron has also produced a plethora of Pûkel-creatures, the most famous of which are his Watchers.

NOTE:Pûkel-creatures are artificial creations that survive only because of the will of their maker. However, they are not true monsters, since they are not perversions of life.
