Slytherin is one of the four houses at Hogwarts School of Witchcraft and Wizardry, founded by Salazar Slytherin. In establishing the house, Salazar instructed the Sorting Hat to pick students who had a few particular characteristics he most valued. Those characteristics include cunning, resourcefulness, leadership, and ambition. The founder highly valued and favoured pure-blood students and the Sorting Hat admitted that it can be a factor when being sorted. The emblematic animal of the house is a snake and its colours are green and silver.
