Hogwarts sorting

Saturn is a witch who starts going to Hogwarts the year Sirius Black escapes Azkaban. She is given she dreamed of. Her own washroom, her own common roon, her own dormitory, her own owlery, and two house elves under her comand. But she gets an anonymous letter her first real school day at Hogwarts saying that she has to meet the person at 9:00 that night. That's not the funny thing. The funny thing is, the anonymous person used her owl to send the letter. Saturn goes to the meeting place and she meets none other than Sirius Black.
