Ahmad Sofian
Ahmad Sofian (unknown - 1176) was a member of the Assassin Order in the Levant, and the father of Abbas Sofian. During the saracen siege of Masyaf in 1176, he was tasked with infiltrating the Saracen encampment. He was captured and forced to give up the name of the Assassin - Umar Ibn-La'Ahad - who had infiltrated Salāḥ ad-Dīn's personal tent, and killed a nobleman during his escape that same night. Ahmad was nearly put to death until Umar stood up to take his place. After he was brought back into the fortress, Altaïr Ibn-La'Ahad blamed him for his father's death.
Some time later, in remorse over Umar's death, Ahmad entered the home of Umar's eleven-year-old son, Altaïr, and remorsefully committed suicide. The truth surrounding the circumstances of Ahmad's death would eventually drive Abbas to develop an intense hatred for Altaïr, which culminated in the former's coup d'état of the Assassin Order in 1225.
