Well, obviously, if Aura had to be unlocked by someone who already had theirs unlocked, there would be the question of "How could the first Aura users get their Aura unlocked if no one had it unlocked before?".

So, equally-obviously, people can unlock it on their own, though not necesarily via trauma. Unless you want to assume almost-every Huntsman in training has some trauma.
