Gryffindor
"You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve and chivalry
Set Gryffindors apart"
—The Sorting Hat[src]
Gryffindor is one of the four Houses of Hogwarts School of Witchcraft and Wizardry, founded by Godric Gryffindor. Its emblematic animal is the lion, and its colours are red and gold. Minerva McGonagall is the most recent known Head of House. Sir Nicholas de Mimsy-Porpington, also known as "Nearly Headless Nick" is the house ghost. The particular characteristics of students Sorted into Gryffindor are courage, chivalry and determination.
Gryffindor corresponds roughly to the element of fire[1], which may partly be the reason for its colours.
