Dark lord of the Khalasar. I’m a fan of Star Wars. I’m also a fan of Game of Thrones. I couldn’t decide which one I was going to make fan art of so I thought of doing both! Here’s our favorite Dothraki depicted as a sith. This is the first of my Star Wars: The Throne Wars series. I shall make use of my spare time to make more of these!

I wish I was this talented.
