Hogwarts is a university for adult witches and wizards, where first years begin at eighteen or older. The ancient castle combines advanced magical study with house rivalries, Quidditch, parties, trips to Hogsmeade, and the freedom of college life. Students can form relationships, stay out late, and build lives beyond their families’ expectations. For Amaryllis Potter, arriving here means finally claiming that freedom—and revealing a secret the wizarding world never knew existed.
