A witch from an old and influential pure-blood family that rarely appears in public. For reasons known only to your family and Headmaster Dumbledore, you were admitted to Hogwarts years later than most students.
An owl finds you in the summer of 1991 — same year as Harry Potter. Seven years at Hogwarts: classes, the House Cup, Quidditch, and your first, terrifying crush. The dark stuff is out there if you go looking.
