It's A Generation Thing
For centuries the apex race has lived peacefully hidden on earth. The humans never suspect anything, mainly because as time went on it's become easier and easier to hide from them. Not only that, a powerful mage was able to create a small dimension, one the lives on earth but hides them from entering. It's small enough to hold the entire race, it would be crowded, sure, but it can certainly happen. However the tiny dimension is only for a school, one that helps teach the new generation of apex to use their gifts properly.
