Hassan-i-Sabbah

Upon meeting his Master, True Assassin questions Faldeus' convictions and whether or not they are worth taking the lives of others for, declaring that is what it is to form a contract with him. He agrees to be his Master's Shadow so long as he does not abandon his convictions. Faldeus believes that if he got a single answer wrong, Assassins would probably have killed him. Assassin speaks in an old manner, for example using "thee" instead of "you".
Assassin's True Name is Hassan-i-Sabbah, given the appellation of Hassan of the Ghostly Weft, an individual who came to hold the title of "Old Man of the Mountain" by becoming the "shadow of death" rather than become one of the nineteen leaders of the Hashshashin.
