In Bestiary 5 there is a monster called a vilderavn which is based on one variant of this mythical creature. The vilderavn is a shapeshifting fey raven knight, but one of the forms it can take (only briefly mentioned) is that of a raven/wolf hybrid. Honestly, I was more interested in that raven/wolf creature than I was in the fey raven knight, so I had to stat it up. My valraven is a CR 6 monster, meaning it will likely be of more use to the GM than the CR 16 vilderavn.
