Ascendance of a Bookworm has really good world building and magic has implicit rules that are upheld throughout the series. The royal academy arc where protagonist goes to school to learn specifically how the magitech works is named Part 4. It begins in 17th book in the series so it’s quite the journey to get to it.
I would talk to the player(s). Playing the outlaw, making disguises, sounds fun.
But also it could introduce racial discrimination into the mix. Y’all would need to be OK with handling that theme.
