Well, from what I can gather, magic is magic. The Magic Kingdom developed it and what was left were those who knew how to use it, which died off slowly over time (possibly because the Held sect reigned supreme; they may have started persecuting witches as payback).

When we translate the conversation in Praeludium between Held and Gumillia, we should get some more insight into it, since Gumillia uses Clockworker Magic to free Kyle. That said, Elluka's statement in Wiegenlied, regardless, is perplexing.
