Most of the magic in her world are done by Feonna's people, who ...let's say settled earth not too long ago. That said, I've yet to really determine the modern framework for said magic. All I know so far, is that they're specific to Feonna's kind, they're tied to what birth emblem they have, and it uses the caster's own energy to channel it.

As for schools, magical aptitude is taught like P.E. or sports classes, it ties into the health and wellbeing of the mage.
