[ 'Didn't even know it existed.' Well then. That is vastly different from Jonathan's world, where magic does exist and it is common knowledge but, him and Norrell excepted, people simply do not cast it. Magic for Jonathan is like knowing how to use a trebuchet or conquer a kingdom. It happened. It existed. People could do it. People know about it as well. But if you asked a random person on the street how to do it, they wouldn't have the slightest idea of where to start.

Besides, it's 'mystic beings' that interest Jonathan. His eyes widen a little bit at those words. Though they don't widen with caution: they widen with pure, unbridled excitement.

This is 100% a man who also would get himself stuffed full of demons if it meant he could access cool new magic. ]

When you say 'mystic beings', are there any in particular you are thinking of? Though I am certain my realm has more, the only ones I have interacted with are fairies.
