GRYFFINDOR'S DORMITORIES
Gryffindor values courage, bravery, nerve and chivalry. Its mascot is the lion, and its colours are scarlet and gold.
The Head of this house is the Transfiguration teacher and Deputy Headmistress, Minerva McGonagall, and the house ghost is Sir Nicholas de Mimsy-Porpington, more commonly known as Nearly Headless Nick.
According to Rowling, Gryffindor corresponds roughly to the element of fire. The founder of the house is Godric Gryffindor.
The Gryffindor common room is located in one of the castle's highest towers, the entrance to which is on the seventh floor in the east wing of the castle and is guarded by a painting of The Fat Lady, who is garbed in a pink dress.
She permits entry only after being given the correct password, as was distinguished in the third book, when Sirius Black tried forcing entry into the tower, only to be blocked by The Fat Lady after he could not give the correct password.
