Magic in Harry Potter
Dark Arts
The Dark Mark is the symbol of Voldemort and the Death Eaters and takes the form of a skull with a snake coming out of the mouth in place of a tongue. The mark is cast into the sky by Death Eaters whenever they have murdered someone. Morsmordre is the spell to conjure the Mark. It first appears in Goblet of Fire and is described as a "colossal skull, composed of what looked like emerald stars, with a serpent protruding from its mouth like a tongue". Once in the sky it was "blazing in a haze of greenish smoke". Dark Marks are also branded on the left forearm of the closest followers of Voldemort. The mark serves as a connection between Voldemort and each who bears it; he can summon them by touching his mark, causing it and those of his followers to burn and change colour. Death Eaters can summon Voldemort in the same fashion. Following Voldemort's ultimate defeat, the Dark Marks on his Death Eaters fade into a scar "similar" to Harry's. In the books, the Dark Mark is described as green; however, in the films, it was only green at the Quidditch World Cup. In all other film appearances it has been grey.
