Don't expect to see magic anywhere. It's so rare as to be almost mythic.
It's also a story mechanic, not a 'nice thing for characters to have'. For instance.. If the story needs a talent (say water cleanser during the plague) and also you're in the right place at the right time and make the right decisions, maybe you'll have the talent of water cleanser emerge. Maybe not. It seems to be story need, not personal desire or affection for magic and special skills.
The way it used to be is that talents would be tied to your soul (which you replay over and over by sparking into new lives after you die), but that was changed. Now the talent expires after a lifetime.
Also, bear in mind that this is a game in development. It's very early so lots of rules and mechanics could change over the course of time. Magic is something that seems pretty firmly rare and not common place or chosen or inherited.
