Salazar Slytherin

Salazar Slytherin was one of the four founders of Hogwarts School of Witchcraft and Wizardry and the least open to the idea of non-magical families sending their children to the school. Slytherin was a talented wizard, and skilled in Parseltongue and Legilimency, who favoured students in particular who showed signs of cunning and ambition. As he became more obsessed with the idea of magical purity, he grew away from his fellow founders and was eventually cast out of the school - but not before he was able to hide a dark secret within the walls of the castle. Salazar's dark legacy (and several of his possessions) would pass down his family, such as his locket and ring.
