Kadar Al-Sayf

Kadar A-Sayf was a journeyman Assassin (neither a novice nor a master), and the younger brother of Malik. From Kadar's words in Solomon's Temple, it is evident that he admired Altaïr's skill and rank

Kadar is uninformed as to why exactly they are in the Temple, thus he asks Altaïr to explain. Altaïr informs him that the Templars had found something in the Temple, and that the master wants them to retrieve it. Later, Kadar finds himself at a digsite together with his brother and Altaïr, where they see some Templars walking around inside. Among them is Robert de Sable, who Altaïr is eager to kill, much to Malik's objections. When Altaïr reveals himself to Robert and the Templars, Kadar and Malik come to join the fight; but after Altaïr is thrown out of the room and forced to leave, it is unknown how long Kadar lasted in battle before he was killed. When Altaïr returns to Masyaf, he informs Al Mualim that Kadar and Malik are dead. However, Malik soon comes in to contradict him, revealing that Kadar had died in Solomon's Temple. Malik, already embittered toward Altaïr for his breaking of the tenets, was infuriated by his brother's death. He believed that without Altaïr's arrogant actions, Kadar would have lived, and he would not have lost his arm.

Trivia

 * Kadar A-Sayf (قدر السيف) translates to the "destiny of the sword."
 * Kadar, like his brother Malik, owned a Hidden Blade. Yet, unlike Altaïr, neither of the A-Sayf brothers had a finger removed. No reason for this has been given.
