Aetheris academy

This is a magic school, the common powers are pyro, hydra, breeze, and earth, then the lost powers are darkness, shadow, light, nature, storm, frost, coloured flame, and a couple others maybe, it's a mix of magisterium and Hogwarts, cause if you get a lost power you get taken to a school, you don't have a choice in that, either go or be taken. You start, but when you get your power you go into a cocoon for that power, a couple days for common, and a week for lost, most lost powers either die in the cocoon or get taken to aetheris academy before anyone sees
