Personal opinion of/c but GOTs identity kinda strives on being the grounded 'realistic' & edgy fantasy.
The novel series plays with unreliable narrators and historical distortion under medieval level historians a lot more, leading some fans to theorize that the world isn't magical, but rather a sort of regressed sci-fi world, with observed magical abilities plausibly being sci-fi concepts related to genetics instead of prophecy.
IMO, it does take a brilliant writer to create a world textured enough that people can dispute the nature of it all, within its own genre conventions.
) he just started training to become a Maester, which he does in the show but iirc they kind of rush the whole thing, their more like scientists/philosophers/alchemists than actual wizards but he is his apprenticing with a Maester who knows ravenspeach which is implied to be kind of magical, and has come into contact with Glass Candles which are basically non-evil lotr Palantirs which I don't think were in the show at all? so he is brushing up against magic a bit
