First Hassan

 The Servant's True name is known as "the Old Man on the Mountain". He also has the moniker of First Hassan. He was the first person to have the title of Hassani-Sabbah, and the founder and first "Old Man". His nickname is King Hassan (kinguhasan or Kingu Hasan?). by Ritsuka Fujimaru, with whom King Hassan is a fan. Even so, his actual identity was unknown even to the 18 individuals who were to be the heirs to his titles. Proof that he in fact existed is not discovered, except for the fact that if ever he who takes the seat of Hassan-i-Sabbah strays from his path, there shall come an executioner who will cut him from his head.There were within the sect of the Hashashin not a single witness who could attest to the existence of the original Hassan; all of those who met him came to their end. The "Old Man of the Mountain", the person who founded the sect was able to remain an observer and to impose a judgment on the deviances and rot. Although the sect remained true to the teachings of Allah however, it was evident that those who promised to continue it were guilty in the eyes of Man. The idea of being affected by the desires of another was, to the Old Man on the Mountain it was a sin against Allah. Therefore the sect's present Old Man would see the end of their leader who is now corrupt. Whatever the case, the fact that the leader had a corrupt spirit or was a decliner in skills or in any other way, this person should not be called the Old Man on the Mountain. To fall meant that you would die. He took their heads in forgiveness of their sin, and handed over hope to the next Man of the Mountain.He took the decision to face-to-face battle with a greatsword , rather than concealed weapons in recognition of his duty to assassinate killers. The sight of his skull mask signified that one's life was over. The skull-masked swordsman brought the hammer to those who disobeyed the order's doctrine and would wipe out anyone who had seen him.
