Cemal, also known as Cem (1459 – 1495) was a pretender to the Ottoman throne, the son of Sultan Mehmed II and the youngest brother of Bayezid II. Secretly a member of the Templar Order, Cem stole his father's Apple of Eden after his failure to secure the position of sultan. Upon proving to be unsuccessful in using its powers, he hid it in the Templar Archive on Cyprus.
As a young man, Cem learned that Sultan Mehmed II, his father, possessed an Apple of Eden and had used it to secure Constantinople. After failing to procure the throne of the Ottoman Empire after his father's death, he took the Apple and looked to it for aid. The Apple, however, did not listen to Cem, nor would it 'speak' to him.
Because of this, Cem decided that the Apple should be passed on to the Templars in the West, to men who had done more research into the artifact's power. Cem was fearful however that when accepting the Apple, the Borgia would shun him, due to him being a more recent convert to the Order. He therefore decided to hide the Apple, until he could establish the Borgia's trust.
Before going to Rhodes to meet with the Templars, Cem hid the Apple in the Templar Archive on Cyprus, and upon arriving at Rhodes, the Hospitaliers arrested Cem and took him before their "Masters in Europe."
After his brother Bayezid became Sultan, Cem was placed under house arrest in Italy, where he became acquainted with Rodrigo Borgia. During these years of imprisonment, Cem wrote to his nephew Ahmet, teaching him, guiding him and shaping the way he thought and acted. It was through these letters that Ahmet learned of the memoirs of Niccolò Polo and the secrets that they contained. Through Cem's directions, Ahmet finally found the memoirs and learned of the library at Masyaf.
Knowing that Cem alone knew the whereabouts of the Apple, the Borgia spent many years persuading and appealing to Cem's better nature, eventually managing to draw the Apple's location from their prisoner. After securing the location of the Apple, Cem was of no more importance to the Borgia, and so they left him.
Cem spent another nine years in various prisons across Europe, before being slain by the Assassin Brotherhood in Capua, who believed that the Borgia were planning to use Cem to conquer Constantinople. However, despite this, the Templars in the Ottoman Empire were unaware of Assassin involvement in Cem's death.
- Ahmet told the Templar Hasan Pasha through a letter that it was Cem who began the project to use the vast knowledge in the library of Altaïr Ibn-La'Ahad to bring peace – through uniting the East and the West into one Empire – and move as one body with one head.
- Cem is a Turkish name meaning "ruler".
