Born the Dancing Dagger, Jei has always been one of the more 'black sheep' of the Clan. Not that he was weird or any sort, but he displayed an incredible amount of aggression from the moment he could walk. And while aggression and violence was natural to Myrians, his easily put him at odds with most of his family members.
It was only made worse when he accepted the flesh of a human from one of the soldiers that had returned from a battle, where he was found to immediately love the taste. From that moment on, his aggressive tendencies became bloodthirsty and ruthless. It had grown to the point that, during the duel that was his Coming of Age Trial, he'd almost slain his opponent, and had to be held back after he'd refused to accept the yield from the (now fingerless) boy.
After his Blooding, he was nearly immediately drafted into the Taloban Army. He'd stayed for his required 3 years and promptly left with a venturing party that was on their way to Riverfall. He was meant to board the ship leaving Taloba, but stayed behind in Syka for... Well, he didn't know, but he stayed. Now he aims to make sure the decision was worthwhile.
