Altaïr returned to the fortress with his fellow Assassins after the retreat was sounded. There, Rauf informed him that Al Mualim had another task for them to perform, but he did not go into details. The two Assassins then headed to the watchtower adjacent to the main gate, where Robert de Sablé had already arrived with his forces, demanding return of the Templar treasure.
Rauf called to Altaïr as soon as the Assassin returned to the fortress.
- Rauf: Altaïr, come. Al Mualim's not done with us yet.
- Altaïr: Where are we going?
- Rauf: Up there. We've a surprise planned for our guests. Just do as I do. It should become clear soon enough.
Altaïr followed Rauf to a watchtower overlooking the canyons by the fortress' walls and gates.
- Rauf: Stand on that platform, Altaïr.
As Altaïr complied, Robert de Sablé and his forces had gathered in front of the fortress, with Robert demanding the return of the artifact, and Al Mualim responding to him from the castle wall.
- Robert: Heretic! Return what you have stolen from me!
- Al Mualim: You've no claim to it, Robert! Take yourself from here before I'm forced to thin your ranks further!
- Robert: You play a dangerous game!
- Al Mualim: I assure you, this is no game!
- Robert: So be it! Bring forth the hostage!
The Templars then executed an Assassin who they had captured.
- Robert: Your village lays in ruins and your stores are hardly endless! How long before your fortress crumbles from within? How disciplined will your men remain, when the wells run dry and their food is gone?
- Al Mualim: My men do not fear death, Robert! They welcome it, and the rewards it brings!
- Robert: Good! Then they shall have it all around!
Meanwhile, Rauf instructed Altaïr further, as Al Mualim prepared to give the Assassins a sign to proceed along with his plan.
- Rauf: Follow me, and do so without hesitation.
- Al Mualim: Show this fool knight what it is to have no fear! Go to God!
Altaïr, Rauf, and a third Assassin performed a Leap of Faith into haystacks far below the tower, though all but the unnamed Assassin came out safely.
- Assassin: Ahhh! Ohhhh! Oh my leg! Aah! Oh my leg!
- Rauf: Quiet, or the Templars will hear us!
Rauf turned to Altaïr.
- Rauf: I'll stay behind and tend to him. You'll have to go ahead without us. The ropes there will bring you to a trap we've set. Go and release it. Bring death upon our enemies!
Altaïr made his way to the trap tower overlooking Robert's forces. With his sword, the Assassin hacked away the bar that kept the tower's cargo at bay, sending several heavy, wooden logs rolling down to cascade into the Templars, killing the bulk of Robert's troops. Following this, the Templars were driven from the village shortly after, and Altaïr was brought before Al Mualim.
- Al Mualim: You did well to drive Robert from here. His force is broken. It should be a long while before he troubles us again. Tell me, do you know why it is you were successful? You listened! Were it that you'd listened in Solomon's Temple, Altaïr, all of this would have been avoided.
- Altaïr: I did as I was asked.
- Al Mualim: No, you did as you pleased! Malik has told me of the arrogance you displayed – your disregard for our ways!
Two Assassins grabbed Altaïr by the arms, restraining him.
- Altaïr: What are you doing?!
- Al Mualim: There are rules. We are nothing if we do not abide by the Assassiyun's Creed: three simple tenets, which you seem to forget. I will remind you. First and foremost: Stay your blade–
- Altaïr: –from the flesh of an innocent. I know.
Al Mualim backhanded Altaïr across the face for his insolence.
- Al Mualim: And stay your tongue! Unless I give you leave to use it. If you are so familiar with this tenet, then why did you kill the old man inside the Temple? He was innocent! He did not need to die. Your insolence knows no bounds. Make humble your heart, child, or I swear I will tear it from you with my own hands!
The second tenet is that which gives us strength: Hide in plain sight. Let the people mask you such that you become one with the crowd. Do you remember? Because as I hear it, you chose to expose yourself, drawing attention before you struck!
The third and final tenet, the worst of all your betrayals: Never compromise the Brotherhood. It's meaning should be obvious. Your actions must never bring harm upon us, direct or indirect! Yet your selfish act beneath Jerusalem placed us all in danger! Worse still, you brought the enemy to our home! Every man we've lost today was lost because of you!
Al Mualim drew a small knife, and stabbed Altaïr in the abdomen after branding him a traitor.
- Al Mualim: I'm sorry, truly I am. But I cannot abide a traitor.
- Altaïr: I am not a traitor.
- Al Mualim: Your actions indicate otherwise. And so you leave me no choice. Peace be upon you, Altaïr.
- Altaïr: Ugh!
The Templars were driven back from Masyaf, and Altaïr was demoted to the rank of novice for his thoughtless actions that led up to the event.
