The world ends when the story ends. That's what the prophecy says. Four souls from another universe. One chance to stop the final doom. Rhea Márquéz was never meant to be part of the wizarding world-but fate dropped her and her three best friends into a life they already knew from books and movies. Now, they're not just students. They're the only thing standing between survival and magical collapse. Heir by magic, not by blood. And Hogwarts has no idea what's coming.
