Jinx that was cast on the posistion of Defense Against the Dark Arts by Tom Riddle. When Tom Riddle went to Hogwarts to become a Professor when the Headmaster Armando Dippet refused him of the posistion, Albus Dumbledore soon after became headmaster then Tom Riddle came back to be a Professor, Dumbledore refused him of the posistion because he knew about his previous deeds. The reason Tom Riddle wanted to come back was so he could watch over his Horocrux in the Room of Requirements. The Jinx was to be lifted when Tom Riddle lifted it, or when the caster died.
