As tempting as the court mage position is, there's no way in hell a manakete walking into a place that runs on genociding and graverobbing manaketes is going to result in anything but bloodshed.
I hate to bring real-world politics into this, but IRL that's only been inevitable when at least some perpetrators of the genocide in question are still actively trying to perpetrate it. Basically every Western nation-state and most other modern states of significant size or age would have been burned to the ground if that were the case.
And if you're saying the Academy
would try to perpetrate the genocide: Some might, but most would recognize that the Marble Hall has nowhere
near the social capital required to get away with murdering an honored guest of probably the second-most-powerful noble on the continent. At best, they'd have a war against Leto's alliance that the Empire refuses to interfere with. At worst, Leto and the Emperor don't get a chance to intervene before other wizards of the Marble Hall excommunicate or execute the assholes who murdered a talented applicant to make a single cool tome.
Ryza isn't some random wyrmling wandering into the lion's den—she's a wyrmling sponsored and protected by Archduke Leto, who has allies within the Marble Hall and armies without. Killing Ryza or stealing her dragonstone would be close to the same level as kidnapping Artemis, and
the Empire knew they needed disposable intermediaries to get away with that.
Well its not like learning their magic is going to help much, though either. Ryza has her own collection of magical knowledge to draw on in the form of experience and the books she has.
That seems like a better starting point to me. Away from a many crazy mages as possible to boot too.
Get some help from local mages, double down on learning manakete magic, go from there.
Ryza is a child, and the books are just books. At best, you're asking Ryza to do the rough equivalent of reconciling quantum physics and relativity from her third-grade science class and some physics textbooks her father kept around. At worst, it's impossible to do what we want to do without understanding human magic. And what we want to do involves replacing or remaking human magic, so the worst-case scenario seems likelier than the best.
Learning from human mages is a good idea. Studying Ryza's parent's scrolls is a good idea. Studying Ryza's parent's scrolls
instead of learning human magic is a terrible idea.
There's a difference between being socially pressured to enter battle every so often, and entering a region whose people who would gladly kill Ryza and ransack her pockets for her dragon stone if her existence was revealed. One of these has us surrounded by allies, and the other leaves us at risk of constant potential ambush.
Because we wouldn't have any allies while heading to the Academy, nor are knights ever at risk of ambush. From the very same enemies you're afraid will attack us on the road, in
far greater numbers to counteract our more numerous allies. The difference isn't that only one option has Ryza entering a region whose people who would gladly kill Ryza and ransack her pockets for her dragon stone if her existence was revealed. The difference is that only one option has her entering a region etc etc
repeatedly.
Though realistically, we're going to repeatedly do that regardless of our immediate choice, because the Empire is an obvious threat and Ryza doesn't like that. So this whole argument is kinda moot.
Maybe is because of the fact that my intro to the game is FE Awakening, but I now have the awkward idea in my head of Arty's descendant just falling in love with Ryza and Ryza just frozen in shock.
