"Death is fasicnating.."
Xiren is almost always smiling in a creepily, happy way. He loves blood, pain and death. Toying with the living and the dead makes him pleased. He is a very whimsical, disobedient fellow. He often butts into matters without being given orders. No one can give him orders other than King Kahn himself. The King is the only one who can control Xiren in any way, but even king's order's aren't always followed exactly by the letter. However, he would never ignore or contradict the king's words.
Light armor and twin long swords, worn on his back. He also carries several daggers and hidden weapons. He also has the bones of a human and a wolf stowed on his person.
Xiren doesn't remember much about his past from before the night he became a slayer. The only clear memory he can recall is of a tall, dark figure crouching over him admits the flames of a burning building and whispering in his ear. "Now be a good boy, Xiren." Then touching his arm as an excruciating pain tore through him and he passed out.
Everything before that is blank. After that he embraced the urges for blood that his body craved. It wasn't long before he discovered his ability to bring back dead things to do his bidding. As time wore on he became better and more and more crazy. When he met Kahn, something about him reminded him of the figure from his memory and swore loyalty to him. Sine that day he has stayed close and done whatever Kahn asked of him.
