<P> Voldemort is the archenemy of Harry Potter , who according to a prophecy has `` the power to vanquish the Dark Lord '' . Nearly every witch or wizard dares not utter his unmentionable name , and refers to him instead with such expressions as `` You - Know - Who '' , `` He - Who - Must - Not - Be-Named '' or `` the Dark Lord '' . Voldemort 's obsession with blood purity signifies his aim to rid the wizarding world of Muggle ( non-magical ) heritage and to conquer both worlds , Muggle and wizarding , to achieve pure - blood dominance . Through his mother 's family , he is the last descendant of wizard Salazar Slytherin , one of the four founders of Hogwarts School of Witchcraft and Wizardry . He is the leader of the Death Eaters , a group of evil wizards and witches dedicated to ridding the Wizarding World of Muggles and establishing Voldemort as its supreme ruler . </P>
