Rashid ibn Musafir
In his mortal days, Rashid ibn Musafir was a farmer near Jerusalem. When the crusaders invaded the city and massacred the population, Rashid became a fervent muslim, vowing to reconquer the city for Allah. Following the Frankish occupation, he bided his time, until he met Habiba al-Sikkeen, an Assamite, who had been wounded during a mission. He tended her wounds and she told him of her nature and mission. She made him her ghoul and embraced him after a series of training.
After his Embrace, he focused on retribution, feeding solely from christians and wreaking havoc among their supply lines. He faded from the public eye after Jerusalem was taken by the muslims.
