After seeing him drawn as a 'Taur, I was curious how Jakob would look as a quadruped. So when  daggerleonelli opened for feral commissions on Twitter, I knew what I had to do.
Here is their rendition of him in a feral wolf form and looking very fine (this would probably require additional magic as it exceeds the limits of his innate shapeshifting abilities). I kept forgetting to upload this, but it's done now!
