Carl the Caring Cadaver

Carl the Caring Cadaver is a Skeleton. Like all Skeletons, by default, he lusted to exterminate life. Life is like fire to Skeletons, burning them with a horrible pain, in a semi-metaphorical sense, and of course it only makes sense they try to extinguish this fire. Another aspect of Skeletons, is that, despite the fact they are not in any way aside from physically the same being as their body originates from, they tend to have similar behavior. The skeleton of a miner might be prone to use a pickaxe, the skeleton of an artist might paint if given tools, albeit without any real artistic meaning or deeper understanding of what it's doing.

Carl's body must've been some sort of connoisseur of card games, because when he came across a deck of cards, he couldn't help himself to pull one out. Not that Carl could read, but the card read "Balance."  Almost immediately after examining this card, he felt a great change come over him. Carl's desire to end life vanished, no, inverted; Carl felt a deep carnal urge to protect life, to serve it even. Unfortunately for Carl, the pain the living caused him wouldn't cease, leaving him in a constant state of torment as he surrounded himself with it. He was adopted into a town, as a mascot for the guard. He patrolled the town, devoting his undeath to preserve those who make it hell. Perhaps he's grown to be masochistic, perhaps not. Either way, it's okay, this is what he wants.
