I also followed the IC here and was hoping to join. My character idea is a female wanderer or sellsword, who's subtle use of control over metal would give her an advantage over stronger, faster fighters. I think I'd give her a knack for getting herself in and out of trouble so it'd be easy to fold her into any overarching plot. Would my metal magic fit in with your worlds definition of magic? It would fall under the category of natural talent I believe.
