That makes sense to me-the last thing you said, I mean. I'll admit, while I'm something of a prodigy myself, the primary reason I was able to master so many spells was because in my world mages tend to have family crests containing the cumulative knowledge of all their previous ancestors who practiced magecraft engraved into their bodies-the longer the lineage, the more powerful the crest. For example, if I didn't have one, I would probably only be able to manipulate water and air currents and perhaps learn a healing spell or two.
