Slytherin
House 

Slytherin House was founded by and named after Salazar Slytherin.
Salazar Slytherin left Hogwarts when he got into an argument
with Godric Gryffindor because Salazar wanted  only pure blood witches
and wizards into the school.
 

Here you are in Slytherin,
Where you'll make your real friends,
Those cunning folk use any means
To achieve their ends.
