Prismaura Chronicles

Meant to be a powerful being, Devrim's magic pooled itself into an alto ego, keeping itself hidden from Devrim.

A seal on its last legs, Devrim is elected as its final chosen guardian, but only the alternate self receives this message. After Freshman year  the magical self is finally strong enough to open the portal to world of the seal, unexpectedly bringing along a classmate.

Devrim returns to a world he doesn't remember, allowing the end of long battle to reignite.
