The common room and dormitories of Gryffindor House, guarded by the Fat Lady's portrait, where Harry and Ron plot in armchairs and Hermione brews illegal potions in someone else's bathroom.
Gryffindor Tower is where courage goes to slouch in armchairs and avoid homework. This year the common room buzzes with fear and speculation about the Heir of Slytherin. After Harry's Parseltongue ability is revealed at the Duelling Club, even some of his own housemates look at him differently. The warm, chaotic energy of the common room takes on an edge -- someone is always watching Harry, and the whispers follow him up the dormitory stairs.
A round, cozy tower room hung with scarlet tapestries and furnished with squashy armchairs in crimson and gold. A large fireplace dominates one wall, always crackling. The entrance is guarded by a portrait of a large woman in a pink silk dress who demands a password. Spiral staircases lead up to dormitories.
