Death Eaters

In Harry Potter, death eaters are followers of Lord Voldemort. They are often cloaked, and wear dark, oddly shaped masks, to resemble evil. They also tend to wear tall, pointed hats approximately half the length of the wearer's height. Death eaters are not to be confused with dementors, the guards of the Prison of Azkaban, which are similar in shape. Death eaters are often spies; they keep their loyalty to Voldemort secret as they are involved with the Hogwarts School of Witchcraft and Wizardry. All death eaters have a snake-like symbol on their arm, called the Dark Mark, to show their identity.

Some examples of dementors are Lucius Malfoy and Severus Snape. Snape, who serves as a professor of potions and chemical spells at Hogwarts, servers the Dark Lord but is also a true friend of Albus Dumbledore, the head of the school. Lucius is the father of Draco Malfoy, a young enemy of Harry Potter and student of the Slytherin House. Draco is also a death eater himself; both he and his father plan the death of Dumbledore as well as Harry Potter.
