Deerfolk
Tywelwyn is a 6'11" deerfolk, with dappled brown fur and tall, branching antlers. His muscles are far larger than could be achieved without magical or chemical intervention, and his skin is hot enough that his sweat sizzles as it's produced.
He is the founder and leader of the Roundhat Gang, a protection racket in Sableclutch. He was rumored to have gone crazy, hearing voices, but it appears that he's struck a deal with someone in Pyrelight. Formerly unable to wield magic, he now pilots a simulacrum to work on his behalf.
