Ahmad Sofian

Ahmad Sofian was a member of the Assassin Order and the father of Abbas Sofian. During the 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 Salah Al'din's personal tent, and killed a nobleman in his escape. 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 to the home of Umar's eleven-year-old son, Altaïr Ibn-La'Ahad, and committed suicide.
