Slytherin "Or perhaps in Slytherin, You'll make your real friends, Those cunning folk use any means, To achieve their ends." —The Sorting Hat[src] Slytherin is one of the four Houses at Hogwarts School of Witchcraft and Wizardry, and is traditionally home to students who exhibit such traits as cunning and ambition. Its emblematic animal is the snake and its colours are green and silver. Founded by Salazar Slytherin, the house is comprised mostly of pure-blood students, due to its founder's mistrust of Muggle-born witches and wizards. The house has a negative reputation, with many claiming that it is the source of most Dark Wizards in Britain, notably Tom Marvolo Riddle, a.k.a. Lord Voldemort, as well as many of his Death Eaters. Slytherin corresponds roughly with the element of water.
