By 1191, Jamal and a Masyaf herald, Masun, had gotten into contact with the Templar Order. They soon started following their ideology and decided to play a role in a Templar attack on the fortress. Being well known in the village of Masyaf, the two of them were able to open the gates that protected the village, allowing a contingent of Templars to enter the Assassins' fortress.
After the Templars had been driven from Masyaf, Altaïr Ibn-La'Ahad sought Masun out and delivered him to Al Mualim. Through his investigations, Altaïr had found out about Jamal, and he passed the knowledge on to his master.
Al Mualim responded that they had to see whether or not Jamal could be redeemed, but he also remarked that that would not be Altaïr's task, as he would get a different mission. Jamal continued to act as an Assassin, standing at his post just outside Masyaf in the countryside.
- Jamal is a transliteration of the Arabic name جمال, meaning "beauty".
- Originally, he was to be an assassination target in Assassin's Creed, but was ultimately cut from the final game due to constraints on Ubisoft. However, he still appears as a minor Easter egg.
- When in Eagle Vision, Jamal appears as the only red enemy Assassin, and if he is assassinated, the other Assassins will ignore it. If he is openly attacked, however, the other Assassins react as any other guard and attack.
- In "The Mentor's Keeper", Jamal could be seen standing guard at the same spot and if viewed through Eagle Vision, would glow red, not blue like the other Assassins.
