Ysengrin is a canine mythic figure similar to Coyote or Reynardine. He carries a particular hatred for humankind, and instead favors the creatures and plants of Gillitie Wood. With Coyote's blessing, he now rules over the trees of the forest with a body of wood, though he almost constantly suffers from tremors because of it. His true body is gaunt and his limbs are weak, though it is unknown if this is because of Coyote's blessing. He loves Coyote and obeys his commands. Jones speculates that he is slowly approaching insanity. He is the former medium of the forest.
