(This is actually one of the discussion threads that I've been intending to reply to for a few days now, [@kapuchu], but due to a multitude of problems (including sleep deprivation) I've held back until now. I wanted to make sure I was at least coherent when I replied; I'm not exactly feeling the best still but now's probably a better time than any.)

While I had a rather lengthy reply in mind for this thread... I've actually decided to avoid posting it here due to the fact that I'd be spoiling (something I have no intention of doing) a pretty significant detail about my main story project if I explained my concept of what "Magic" is here. Due to that, all noteworthy information I give about that project will only be done over PM for the time being. All I'll say for the time being is I found this thread interesting, mostly because I usually like to see different people's ideas for magical concepts. My own is something I consider particularly unique in some ways, so I won't be commenting here by relating to it (meaning I don't have much to say), but since no one else had posted here I figured I might as well say something.

I will note that there's some parallels between a bit of what you've written and some of my own concepts and ideas (which I've been working on for decades) actually, though I'm perceiving that there's some noticeable differences too. Admittedly, I'm still not feeling particularly coherent, so I can't give my best analysis.
