Luna shook her head, "Changelings merely use a kind of mind magic. They certainly aren't the source of it at any rate. Still though, it does look remarkably similar to changeling magic, so one has to wonder which came first, the magic or the changelings? Faust could easily be old enough to predate the changelings, and might have had a hoof in their creation if what Twilight told me about her first meeting with Faust was true."
