Something just occurred to me, how does medicine work in the realm of various fantasy worlds? Specifically medicine and magic. If someone loses an arm, couldn't the doctors use magic to weld it back to the stump or generate a new arm? I've seen some fantasies where it's explained that magic can't heal something that's already healed (like a scar, for instance) or make what never was (say generating hearing for someone born deaf.) Sometimes I've seen it where the magic in regards to medicine is downgraded in lieu for the more "muggle" way of medical treatment. My questions for you all are: - If you're writing a fantasy with magic, do you put restrictions on your magic in terms of medical care and other things to ensure they're not too overpowered? - Do you think it's logical that in some works of fiction, magic can do all sorts of amazing things, yet it can't glue a severed arm back to the stump, heal a scar (Thanks, Dumbledore!) or generate hearing for someone born deaf? It's magic, right? Is it realistic that in a world with magic, it's limited to only a few certain users or by the condition of the injury/condition? I hope I made some sense, I just wrote this off on the fly because the thought had sprung in my head.
