Ludo entered the Common Room and sat in a high back chair next to the Announcement Board. His gaze traveled to the ceiling covered in stars.

He looked around the room and saw Mari at one of the tables. "Hey Mari." he said, with a slight wave. "Your classes going well?"
It was then that a notice on the board caught his attention.

Dueling Club...Room of Requirement. he read. His eyebrows raised. He remembered something.

"Room of Requirement! That's what Jaques'd been talking about. Seventh floor Room of Requirement, of course!...I wonder how you get in...surely someone knows." he thought.
