Editing Ezio Auditore da Firenze (section)

====Fight with Prince Ahmet====

After arriving in Constantinople, Ezio hurriedly made his way to Sofia's bookshop. He found that the place had been ransacked and Yusuf, whom Ezio had asked to look after Sofia during his time in Cappadocia, had been killed. Upon discovering Yusuf's dead body, Ezio gave him a final blessing before shutting his eyes. Declaring a renewed vengeance against all those who dared to cross the Assassins, Ezio collected the remaining Keys and prepared to ambush Ahmet during the exchange.

However, Ahmet held Sofia hostage atop Galata Tower, and Ezio was forced to give him the Keys in order to rescue her. The hostage turned out to be Azize, one of Ezio's fellow Assassins, and Ezio saw Sofia was being hung in a courtyard.

After parachuting down towards her, and after ensuring that she was fine, Ezio boarded a carriage with to pursue Ahmet, who had already hurried off towards Syria to find the library and unlock its contents.

After a lengthy ride through the country, which left Ezio essentially parasailing to hang onto their carriage, he managed to grab Ahmet and the two struggled as they both went flying off a cliff. Ezio subdued the prince and opened a parachute to save them both.

As they both recovered from their rough landing, Ezio and Ahmet saw an army arrive with Selim at its head. Selim explained that the Sultan had chosen him over Ahmet, and proceeded to strangle his brother and throw him off a cliff. Selim spared Ezio, having heard good things about him from his son Suleiman, but ordered him to stay out of Constantinople.

After traveling to Masyaf with Sofia, Ezio used the five Keys to open the door to Altaïr's library. Ezio discovered there were no books, only the body of the former Mentor, with a memory seal in his hand. The seal revealed Altaïr's final moments, and the location of his Apple at the back of the library.

Ezio moved towards the Apple, but refused to take it, believing he had seen enough for one life. The Apple emanated a wave of light, and Ezio began speaking to Desmond. Acknowledging he was a conduit for a message, Ezio removed his bracers and sword to declare the end of his life as an Assassin. He then encouraged Desmond to make his life's sufferings worth it, and told him to listen.
