While not canon, Taur Jakob is rather fun. Here's a rendition of him by Ahro, drawn as a Patreon sketch and coloured by me.

On a whim I gave him blue claws - nobles among Vernor Vinge's Tines would paint their claws so I see no reason Jakob shouldn't. One day I'll figure out where his clan mark goes in this configuration, but apparently today is not that day. Most likely the next time Jakob Taur goes for a spin he'll be wearing shiny clothes and the marking will be a moot point.

Lines by colour by me.
