Samiel is an original character based in the Shin Megami Tensei: Digital Devil Saga universe, and played on YouAreHereMUX. His demon for is Taraka (who's in my scraps folder until he's finished), and his seal is the Savage Hurricane (or at least that's what I'm calling it until I can think of something better). He's Force-elemental.
A bit of trivia, a samiel is a term for a particular sort of sandstorm.
I worked fairly hard to duplicate the shading of the real characters in the game. It's not perfect, but it's close, I think.
