Lord Slytherin was one of the four founders of Hogwarts School of Witchcraft and Wizardry. He is known for his ambition, cunning, and resourcefulness. Slytherin valued pure-blood lineage and believed that only those from magical families should be allowed to learn magic. This belief led to a lasting legacy of rivalry with the other founders, particularly Godric Gryffindor. Slytherin's house, Slytherin House, is represented by a serpent and is known for producing many powerful wizards, including Tom Riddle, who later became known as Lord Voldemort. The house values traits such as ambition, leadership, and determination, which continue to influence students at Hogwarts today.
