Antihogwarts

I'm catching  up on the second season of Magi, and I've stumbled across what is essentially antihogwarts.  But rather than a school, it's a whole country.  And rather than deatheaters just killing them damn muggles (...those amateurs), these people are sucking their life force to fuel the magician's way of life.

I know this is suppose to be a kids anime, but... damn.
