Pledge your loyalty to Slytherin™ with this magical house banner! Display the Slytherin crest on the wall or open the banner to 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 Black Lake scene. Search for the secret message. But beware of the eyes watching your every move!
