An ephemeral effigy created and inhabited by an old trickster spirit.
Koyotl is my take on Coyote from folklore. He would appear something like this in my spirit lands. Like typical trickster figures, Koyotl is neither benevolent or malevolent, choosing to stick to the grey areas. At some point in history, he gave up his physical form and took up an existence in the dream plane as a dream walker. Thanks to his massive level of spirit energy, he is able to play pranks on those in the conscious world by manipulating the underlying fabric of reality. Even though he no longer has a real body, he can create pseudo-physical effigies of himself using a limited amount of energy and interact directly with conscious spirits. Once the effigy depletes its reserves, it fades away and Koyotl returns to the dream plane.
