What in the world? Gwen had been lost. She knew her common room was supposed to be on the seventh floor, but she had gotten separated from the group. She had walked up and down this hallway more than once trying to find the rest of the Ravenclaws. All of a sudden a door had appeared in the wall, and Gwen had curiously pushed it open to reveal a small little room that most certainly hadn't been there before.

There wasn't much in it, a lamp and a table, but on the table was exactly what she'd been searching for, a map of this very large, very confusing school. Gwen picked up the map, located her common room on it, and headed back out in search, map in hand.
