​

 Slowly you awaken; you vaguely remember falling into a hole. Beneath you is a giant pile of bones. 'Chicken!?' You think hopefully. Looking around you see damp stone walls and a large stone statue of a man.  You're trapped in the Chamber of Secrets!  "

Suddenly you hear a faint hissing.  

The Basilisk.

You see a tunnel with a dim light at the end to your left. You run towards it only to bounce off a magical ward! It was cast with Arithmancy, the study of the magical properties of numbers. You need the correct sequence of numbers to dispel the ward! ​

​

 Certainly, the wizard or witch who cast this left clues behind in case they forgot!
