Tharkay

Here you have a picture of Tharkay, the mysterious character from Naomi Novik's Temeraire series that makes his first appearance, if I remember correctly, in Black Powder War. I like Tharkay because he is cool and shrouded in mystery, and you never quite know when or where he's going to pop up. I also like his personality, and how he seems to be the exact opposite of Laurence when it comes to grabbing the dragon by the horns, so to speak. He is honor- bound... to himself, which makes for an interesting interaction between him and Laurence.
At any rate, I hope you like the picture!
