Deatheaters

The Death Eaters (originally the Knights of Walpurgis) was the name given to the most loyal and high ranking followers of Lord Voldemort.

They often wore black hoods and masks with snake-like eye slits to cover their faces. Only the members of the inner circle of the Death Eaters had Dark Marks burned into their left forearms. When Voldemort touched one of them, each of the Death Eaters felt it, signalling for them to Apparate to their leader's side.
