An excellent kill. Fortune favors your blade.
——Kadar complimenting Altaïr.[来源]
What is our mission? My brother said nothing to me, other than I should be honored to have been invited.
——Kadar pleads for information from Altaïr.[来源]
A short while after, Altaïr assassinated an innocent man close to the entrance of the Temple and incurred the wrath of Malik, as the lower-ranked Assassin berated him for dishonoring the Creed. This warning to his idol went over Kadar's head though, as he ignored his brother and praised Altaïr for his skill with the Hidden Blade. Following this, as Malik was frustrated by the turn of events, he left to scout ahead out of exasperation, while Kadar further flattered his role model.
The three Assassins continued through the tunnels, leaping over pits in the ground and killing one guard that stood in their way without raising an alarm. Eventually, they found themselves on a stone, earthen ledge overlooking a large room. The walls were held back by beautifully carved pillars and a highly-decorated golden box was shown above an excavated entrance on the opposite side of the room. Accompanying this, several scaffolds had been left about the place, as the chamber had only just been dug out by workmen from Jerusalem.
Malik pointed out the decorated box and claimed that it must be the treasure they were looking for, to which Kadar hesitantly asked if it was the Ark of the Covenant, but was lightly chastised by Altaïr as being silly, as the Ark was nothing but a fairy-tale. Suddenly, a group of Knights Templar walked into the room below, unaware of the Assassins above them. One of these was Robert de Sable, the Grand Master of the Templar Order, and sworn enemy of the Assassins.
Altaïr immediately declared that the life of Robert was his, despite Malik arguing that their mission was to retrieve the treasure, not to kill Robert. However, Altaïr called him a coward and approached his target nonetheless.
Making himself known, the Assassin openly challenged Robert, going against the second tenet of the Creed which ordered Assassins to always be discreet. However, Robert seemed unfazed to see the three Assassins and easily fended off Altaïr's attack, separating him from Malik and Kadar by throwing him through a wall, with the intention of sparing him on purpose so that Altaïr could deliver a message to Al Mualim.
- Malik：“Gone... because of you!”
- Altaïr：“Robert threw me from the room. There was no way back, nothing I could do.”
- Malik：“Because you would not heed my warning! All of this could have been avoided! And my brother... my brother would still be alive!”

Unfortunately, Kadar was not experienced enough in battle to survive the onslaught of so many enemies at once and perished, although it was unclear whether Malik fled before or after this event. He did not leave unscathed however, as Malik's arm was injured severely enough to need amputation upon his return to Masyaf.
- Kadar：“The Ark... of the Covenant?”
- Altaïr：“Don't be silly, there's no such thing. It's just a story.”
- ——Kadar views the Ark with astonishment.[来源]
Kadar的年龄比Malik小，但是他的级别比新手高，在他小的时候，他很有刺客的天分，他有着独特的战斗风，他非常努力的去跟上Malik，他敬佩Altair。卡达尔认同刺客的信条并服从信条，虽然欣赏Altair的傲慢和鲁莽的方式，但他认为一个刺客需要履行其致命任务的谦卑和耐心。 由于他所出生的国家，Kadar晒得相当黑，Malik也是如此。在他的嘴唇和下巴有一些胡茬。他的眼睛是非常奇怪的光色，而不是中东人的更为常见的深褐色的眼睛。他的头被大多从视图中隐藏在一个灰色的兜帽中，他的深灰色袖子告诉了我们他的低级别。 他的刺客长袍是马斯亚夫卫兵常穿的短袍，三角形带扣是绑在胸前，一个红色的腰带是系在腰间。飞刀则留在他的皮带和一把剑挂在腰间的左侧，虽然他被赋予了袖剑，但是Kadar并没有切断无名指，这在刺客中很少见。
