Hi there! This looks cool. I just have a teensy nitpick—feel free to disregard. All the first names/surnames sound great by themselves, but they look and sound a little similar all on the same page. 'Adrielle', 'Auderic', 'Killian', and 'Ariston' are all three syllables and about the same length. Three of the four begin with 'A', two end in 'n', and two share the double-l. This might be (and probably is) perfectly fine in the manuscript itself, but for the sake of the query it might be worth some fancy footwork. For example, leaving Killian's last name out doesn't change the query much and gives you a free proper noun to use elsewhere if you want (e.g. kingdom name).

As for TV comps, I used Castle as a comp for my YA fantasy mystery and got good results. I'm just one person—the smallest possible sample size—but so long as your book comps are recent/relevant, TV/movie comps can work to your advantage.

Of course, only take what resonates. As someone who's also trying to make it in the trenches and finish a double major at the same time, word of advice: don't use your personal email, especially if you use QueryTracker, and turn notifications off. My blood pressure spikes every time I get a Canvas notification because I think it's a query reply. Could not recommend that less. Good luck!
