Hi, came into this a bit late, but I'd like to join if you'll have me. I don't have a CS written up yet, but my current idea is that my character comes from a magically-technological world (think steampunk magical girls).

He is a ball-jointed doll automaton given life, so kind of an evil Pinocchio/cursed doll on a rampage. His creator actually finds the shard first, but unwittingly uses it as the doll's power source, giving the doll the ability to consume his plane's particular brand of magic and technology, and continue to add more and more parts to his body to feed the emptiness he feels from his negligent creator, until he's turned his entire world into a factory to keep making replacement parts for himself. He would see Chaos as his true creator and 'Father', and the other archons as his true 'siblings'. He would be cute, precocious, and sociopathic.
