Is this a misrepresentation in Oblivion, or is it correct that in Elder Scrolls about 90% of the citizens have at least some degree of magical aptitude? - If so where do they get it from, are they taught it in school? By their parents? Manifests naturally on it's own? - How common are people with no magical aptitude at all? (In a world where people can click their fingers and set your hair on fire, having no magical abilitity at all would be a huge if notlethal disadvantage), it's strange that despite the fact everyone seems to have proficiency in at least 1 school of magic the world doesn't seem all that different, you'd expect there to be cultural difference when people can levitate, teleport, turn invisible or throw fireballs.
So, what's the deal? - Did Oblivion just goof that in giving everyone 7 majors, civilians end up invariably with at least 1 school of magic, or is it really so magic rich most citizens know at least 1 cantrip? - And if so, why does none of the trained warriors seem to know any cantrips when the average civilian does?
