Soulless Wolf
Viruhk-Ur claims to be one of the Firstborn.
Soulless Wolf is the Totem spirit of the Bale Hounds.
Ban
Soulless Wolf is unable to leave the area of a Wound. The spirit can discorporate and return to whatever existence the spirit-gods of sin have set aside for the Eyes of the Maeljin, but, when manifested in the Shadow, the spirit is bound for some unknown and unknowable reason to Wounded areas of the Shadow. Some say this lends serious credence to the notion that Soulless Wolf is not a true Firstborn, but rather a Maeltinet spirit born (or warped) into the shape of one of Father Wolf's children to suit the Maeljin's purposes. Others point out that each of the Firstborn suffers a ban, as all spirits, and Soulless Wolf's is no more restrictive than many.
