Knowledge (Masun)

Knowledge (Masun) was a virtual representation of one of Altaïr Ibn-La'Ahad's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Altaïr brought Masun before Al Mualim. The traitor showed no regret for his actions and no desire to atone for them. He was promptly executed by Al Mualim afterwards. Altaïr earned the right to carry a sword and a Hidden Blade once again, and was tasked with eliminating nine men throughout the Kingdom, starting with a black market merchant in Damascus, Tamir.

Dialogue
Masun was brought to Al Mualim's study, where Altaïr's Master offered him one chance to give up his Templar ways. Al Mualim killed Masun by stabbing him through the neck with a sword, all the way to the hilt, and handed it to Altaïr afterwards.
 * Al Mualim: You stand accused of betraying our Brotherhood and opening the way for our enemies. How do you answer to these charges?
 * Masun: I deny nothing. I'm proud of what I did! My only regret is that they failed.
 * Al Mualim: I offer you a chance to repent. To renounce the evil in your heart.
 * Masun: It is not evil in my heart, but truth! I will not repent.
 * Al Mualim: Then you will die.
 * Al Mualim: You did well, Altaïr, and have earned the right to carry a blade once more.
 * Altaïr: What will become of the one who helped him?
 * Al Mualim: That remains to be seen. Some do ill out of ignorance or fear. These men can be saved. Others suffer from corrupted wills, their minds poisoned and twisted. These men must be destroyed. Soon enough we'll know what sort Jamal is.
 * Altaïr: I've passed your test then. What now?
 * Al Mualim: Oh my child, we've only just begun. I hold here a list. Nine names adorn it. Nine men who need to die. They are plague-bringers, war-makers. Their power and influence corrupts the land and ensures the Crusades continue. You will find them. Kill them. In doing so, you'll sow the seeds of peace. Both for the region, and for yourself. In this way you might be redeemed.
 * Altaïr: Nine lives in exchange for mine.
 * Al Mualim: A most generous offer, I think. Have you any questions?
 * Altaïr: Only where I need begin.
 * Al Mualim: Very well. Ride for Damascus. Seek out the black market merchant named Tamir. Let him be the first to fall. Be sure to visit the city's Assassin Bureau when you arrive. I'll dispatch a bird to inform the Rafiq of your arrival. Speak with him, you'll find he has much to offer.
 * Altaïr: If you believe it best.
 * Al Mualim: I do. Besides, you cannot begin your mission without his consent.
 * Altaïr: What nonsense is this? I don't need his permission! It's a waste of time!
 * Al Mualim: It's the price you pay for the mistakes you've made! You'll answer not only to me, but all the Brotherhood as well now.
 * Altaïr: So be it.
 * Al Mualim: Take your equipment and go. Prove you are not yet lost to us.

Outcome
Masun was executed by Al Mualim. Altaïr's hunt for the Nine began.
