Robin

He has a particular aptitude with animals, dragons in particular. His brother shares this trait with him and they both compete over who can make the best book on dragons, they compete over this, and travel to different regions to explore and find dragons they haven't seen yet.

He's usual quite quiet in large groups of people, though he's fine with this and will listen to the conversation, sometimes adding bits to it. Until someone asks him for his opinion on something, at which point he seems to loose himself and stutters over himself, sometimes having to restart his sentences.

He has a pet Arctic Howler named Dino-Fuzz. Thinking back now, he wished he had given her a different name, but its stuck now. He just calls her Dino.
