I see you've found Serena's Room. Serena is a witch in training. She's a fourth year student at Hogwarts and one of the few American witches here. When she's at school she stays in the Gryffindor House when class is in session, has a huge crush on Professor Snape (shh, don't tell her classmates.), her wand is   Unicorn Hair, Yew, 9 inches  , her favorite class is Divination,  and she's a Chaser on the Quidditch Team. She dated Fred Weasley (Ron's brother) briefly and though they broke up after she had a vision of her  soulmate (second sight runs in her family) they are still good friends. Serena's only been living here for two years and she doesn't know the way out She'll just fly out her window with her broomstick when she needs to leave.  I guess you'll have to find another way out. Click on the door to leave.
