This spell conjures the Dark Mark. It was apparently invented by Lord Voldemort. It is used by Barty Crouch Jr. in GoF. Also used in Harry Potter and the Half-Blood Prince over the castle to lure Dumbledore to his death. Comes from the Latin words mors meaning death, and mordere, meaning to bite; this is obviously associated with the name of Lord Voldemort's followers, the Death Eaters. Ironically, this means "mother's murderer" in Norwegian, and "bite, to bite" in French.
This spell fills peoples' ears with an unidentifiable buzzing, to keep them from hearing nearby conversations. It was created by the Half-Blood Prince. It is used in Harry Potter and the Half-Blood Prince by Harry and Ron on various teachers and people such as Madam Pomfrey, while Hermione refused to use any of the Half-Blood Prince's spells.
