Show your dedication to Slytherin with this magical dormitory banner! Place the Slytherin crest on the wall or open the banner and join Draco Malfoy, Pansy Parkinson, and Blaise Zabini in the underground Slytherin common room. Sit by the flickering fire and look out the window at the underwater scene of the Black Lake. Search for the secret message. But beware of the eyes watching your every move!
