It seems like the first rule of magic, or at least the first limitation mentioned, is usually ‘you can’t bring back the dead.’
And I know it makes sense from a writing standpoint, but I also wonder if it comes from somewhere else. If that’s just the first, most common human response to hearing that magic is possible.
Maybe the first question was, ‘Are the dead still going to stay dead?’ for so long that people stopped needing to say it, that it just got answered right away. Yes, the world will still hurt. Chin up, you can make fire from your fingertips. Maybe you can hurt it back.
