I'll say this first, you won my subscription.
Now for my feedback:
The exposition in the first two episodes felt a bit heavy. Like I was reading a text in school, you know? Its not that the information wasn't interesting, because it was and I like it. But as far as story telling I was put off a bit, I didn't immediately become interested. If not for this post being where I discovered you, I may have drifted away before the second episode.
Of course, I am impatient. Many aren't.
IMO It would feel more engaging if you kinda led me into the world mechanics slowly. Every time you said "this world" I was reminded I was reading a book, you know? Breaks the immersion for me. If you would've started the entire series by describing Diarem walking through the hallway followed by that paragraph "The worst subject for non-magicians..." then I would've instantly got caught up in the story. The expositions could have some in smaller increments as events unfolded. Just my opinion though, I'm really enjoying it so far.
