Great Angry Wall

Description
Curious of Basilisk's motives, Altaïr followed him to Tyre.

Dialogue
Hamid pointed to the nearby wall. Altaïr made his way along the outside of the wall, before noticing a gap in the wall, impeding his progress. Altaïr noticed a couple crates on a lift higher up. Altaïr removed the crates, causing the lift to raise, lowering a bridge below. He crossed the bridge and found his way to an entrance in the wall above. Altaïr used his grappling hook to make his way to the lever, opening the gate. Upon entering the gate, Altaïr was met by a crossbowman. Altaïr killed the crossbowman and proceeded, meeting more guards along the way. Altaïr continued, finding his way to a cage and alerting a nearby guard and his prisoner. Altaïr pulled the lever, freeing the prisoner. Upon his return, Altaïr was met by more guards. After disposing of the guards, Altaïr spoke with the prisoner. With the prisoner's aid, Altaïr freed the man's brother. The proceeded to help by lowering a drawbridge. Altaïr made his way toward the key-holder. Eliminating the guards, Altaïr continued on, coming to a platform and a few crates. Counterbalancing the platforms, Altaïr crossed over and came upon more guards. After killing the guards, Altaïr pickpocketed the key-holder and opened the door to the Templar's Hold. Altaïr used his crossbow to eliminate the sleeping guards and made his way to the rooftops. Once there, he surveyed the area. Altaïr removed the weight, made his way across the platform and interrogated a guard. Altaïr left the man and arrived at the city gate. Altaïr made his way down to Basilisk, engaging and defeating him in battle. Altaïr navigated his way through the courtyard and pulled the lever. Altaïr scaled the wall and traversed the rooftops until he reached a gate. Altaïr pushed the boxes onto the switches, opening the gate and allowing him to proceed. After dealing with the guards outside, Altaïr finally caught up with Basilisk. Altaïr and Basilisk fought, resulting in the former's victory. Altaïr exited the Templar's Hold and made his way to the docks. Altaïr arrived at the docks and surveyed the area. Altaïr killed the Templars and set the ships ablaze.
 * Hamid: Welcome, Altaïr.
 * Altaïr: Thank you, Hamid. It's good to be back alive.
 * Hamid: What do you need?
 * Altaïr: I have to find Basilisk.
 * Hamid: Well, that could be a problem. We had two men who had access to the Templar's Hold. But they were captured not long ago.
 * Altaïr: How do I find them?
 * Hamid: Along this wall, on to the west side of the stronghold's wall. Be careful, the way is very treacherous.
 * Altaïr: I need something to continue this way...
 * Altaïr: Hmm... It seems that I have to remove that weight...
 * Altaïr: Now I can pass and move on.
 * Altaïr: Finally, a gate! But it seems closed. I wonder where I can open it...
 * Altaïr: Good! But this is only the first step. I'll return to the gate.
 * Crossbowman: Stop where you are!
 * Guard: Go! After him! Kill him!
 * Prisoner: An Assassin! Finally! You have to open the cage! The lever for this one is there!
 * Crossbowman: Attack!
 * Prisoner: Thank you, Assassin. I owe you my life!
 * Altaïr: I need a way into the Templar's Hold.
 * Prisoner: Straight to the point, eh? My brother can help you.
 * Altaïr: Where can I find him?
 * Prisoner: In a cage, further down the wall. I'll help you release him.
 * Brother: Thank you for releasing me! What is it that you need?
 * Altaïr: A way into the Templar's Hold.
 * Brother: A fair trade, then. The last gate down this wall. Get the key from the nearby guard to open it. That is your way in. Good luck!
 * Guard: Stop where you are!
 * Altaïr: I'll use this to raise that platform.
 * Guard: Don't let him escape!
 * Altaïr: The Templar's Hold, at last. Basilisk should be around here somewhere... That ladder should lead me onto the rooftops. I will be safer there.
 * Altaïr: The boxes, their weight is keeping the other platform raised...and I must be careful of that man too!
 * Guard: Stop it! I'll tell you everything!
 * Altaïr: Where is Basilisk?
 * Guard: Eastward, you'll find him somewhere around the city gate.
 * Altaïr: That's a bit too open for my taste. Narrow it down.
 * Guard: I can't The man is driven by a thousand crazy horses, always moving, always poking around.
 * Altaïr: Basilisk!
 * Basilisk: You survived?! How interesting and challenging, Assassin. Men, don't let him pass! Close the gates! Come, fight me!
 * Basilisk: A lucky hit, Assassin. It'll put me on the run, but not for long. Curse you, Assassin!
 * Altaïr: I must hurry if I'm going to catch Basilisk! Templar archers, better be careful! And a trap that blocks my path. Maybe that handle stops it.
 * Altaïr: Now I can pass through.
 * Altaïr: A closed gate. There must be a way to open it. These boxes should serve the purpose well enough.
 * Guard: There he is! Catch him now!
 * Guard: He's here! Kill him!
 * Altaïr: Basilisk!
 * Basilisk: You! Following me everywhere, it's getting tiresome!
 * Altaïr: Come, I'll end this forever!
 * Basilisk: Wait! Stay your hand and listen.
 * Altaïr: What do you want?
 * Basilisk: I'll offer you two pieces of information for sparing my life. The first one is the location of the Chalice.
 * Altaïr: Go on, I'm listening.
 * Basilisk: Jerusalem, in Don Carvaggio's villa. The second one is about the city of Acre.
 * Altaïr: What about it?
 * Basilisk: We've been laying siege to it. But it's growing tiresome and...
 * Altaïr: And?
 * Basilisk: ...there's a plan to poison every water source in the city. Everyone will die. The city will be empty before sunrise. I think it's a challenge worthy of an annoying Assassin such as yourself. Stop the poison plot in Acre. Then run to Jerusalem for the Chalice. All before I get to the Chalice, of course.
 * Altaïr: ...I'll accept, but I'll also make sure Basilisk doesn't make it out of the city. Okay, it's a deal, Basilisk.
 * Basilisk: Good luck, Assassin.
 * Altaïr: I should reach that spot and enter there. That crank seems to be the key...
 * Altaïr: ...Basilisk's ships! ...and some Templars... I should use the torches to burn down his ships.
 * Templar: Don't let him approach!
 * Altaïr: I'm done here! Now, the poison plot and then the Chalice!

Outcome
Altaïr burned Basilisk's ships and set out for Acre to stop the poison plot.
