Gryffindor House was founded by Godric Gryffindor, one of the four founders of Hogwarts School of Witchcraft and Wizardry. Gryffindor demanded that you had to be brave, courageous, daring, and chivalrous. If you didn't have these traits, you didn't belong in Gryffindor. The head of house is Minerva McGonnagal, the ghost is Nearly-Headless Nick, and the Gryffindor colors are scarlet and gold. Gryffindor House is represented by a rearing lion.
