Camus Peligor is the CEO of Peligor Corp and former student of the El-Melloi Classroom under Kayneth El-Melloi Archibald.
Camus was a student of the El-Melloi Classroom in the 1990s under the tutelage of Kayneth El-Melloi Archibald. She suffered an accident around the time that her professor died, where she was attacked and scarred by a Griffin, and as a result her Magic Circuits have been damaged and she was kicked out of the Clock Tower. While it isn't clear, it is possible that her classmate, Amleth Wotan, was the culprit behind her accident or that he simply ended up causing it by accident.
