"Ugh!" Harry grunted, as he landed at the bottom of the slide. Moving quickly he got out of the way as Hermione, Ginny and Ron followed behind him. Standing up, he looked around and was mildly surprised that the chamber was fairly well lit. He glanced around, and finally saw Luna lying on the floor about 20 yards away, a figure moving around her. There was something odd about the figure, but Harry couldn't quite tell what it was.
