Kellis

=Physical Description=
His hair is a sickly green, a byproduct of his death and subsequent rebirth. He carries himself proudly, usually seen garbed either in the robes of a Dalaran mage or in some set of robes he'd sewn himself. His jaw hangs loosely, a result of the way in which he was killed. His eyes are generally a glowing yellow, another byproduct of his unlife.
Most recently, his lower are has some small golden flakes in it. Were he to pull up his sleeve, you could see that his elbow appears to be made of solid gold.
=Personality=
Kellis is, first and foremost, a professor, which entails a set of duties he takes seriously. Whenever someone says something incorrect, or that he disagrees with, he will correct them, a habit that doesn't earn him many friends.
But, if you do manage to work past that tendency, he is a very caring person, a habitual worrier, and a staunch friend. He is someone you can count on in a pinch to help you, bail you out, or do whatever he can for you.
Most likely his biggest flaws are his tendencies towards jealousy and self-pity. He lost a loved one just before he died, and blames himself for it against all evidence to the contrary. Even with that, he becomes intensely and quietly jealous of anyone who appears to be happy with someone else, or cheerful in general.
Most recently, though, he's become much more confrontational and glib, almost seeming to be picking fights. He's become extraordinarily protective of his privacy and personal space, to the point of threats if either of those are threatened.
He also is cultivating a dislike for elves.
=History=
Born in Strahnbrad, Kellis was a bookish sort. As soon as he was of age, his parents sent him to Dalaran for magical studies, where he took to the studies of the Light like a duck to water. Once he graduated, he went back to become a professor, in the process meeting his fiancee-to-be, Rachael. He became a professor of the Holy Light at the college at Dalaran, and quickly set to work training paladins and clerics in the best way to manipulate the Light to their needs.
Then the Plague hit. Everyone fled, and Kellis not only lost Rachael, but his own life after a while. He then woke up in Deathknell, with no recollection of what had happened, but an imp watching over him. Since then, he's managed to regain his memory, but holds it close to his chest, not liking to tell just anyone what exactly had happened to him.
