Rickets is an undead skeleton trained to be an assassin. From a very young age, he was trained with all the skills needed to kill quickly and quietly, which eventually made him numb to the sight of blood. One day, one of his assassination attempts went horribly wrong, and when he was caught, he paid the ultimate price for his mistake. Still, his trainers thought his skills would be a waste if he's dead, so they called upon aid from dark forces to bring him back.
