Selim III (24 December 1761 – 28 July 1808) was the Sultan of the Ottoman Empire from 1789 to 1807.
Sometime before 1805, Selim came into possession of a Piece of Eden called the Koh-i-Noor. At some point, Selim took a man named Ahkbar into his employ, making him into one of his spies. Sometime after, Tavis Olier, the Black Cross, infiltrated Selim's palace in Tripoli in an attempt to retrieve the Koh-i-Noor. However, Tavis was caught and, despite Ahkbar's suggestion to kill him, Selim decided to imprison Tavis in case he would ever need him as a bargaining chip.
In 1805, Ahkbar tricked Jan van der Graff, an agent of Napoleon, and Solomon Bolden, the new Black Cross, by giving them directions towards a tunnel where he and several men ambushed them, which resulted in Ahkbar killing Bolden and van der Graff being captured. Afterwards, Selim approached van der Graff after his interrogation and was informed by Ahkbar, who had supervised the interrogation, that the Flemish was not a Templar like Bolden and knew nothing of the true power of the Koh-i-Noor. However, Selim remarked that the Templars could have been using van der Graff as a tool without him being aware of it and ordered him to be thrown into the cell of Tavis Olier, who then trained the younger man in the Templar ways.
In 1808, Selim was informed by the Libyan Assassins that they intended to buy the Koh-i-Noor and expected him to deliver the relic to them. However, Selim refused to hand over the relic, believing that its power would allow him to withstand both the Assassins and the Templars. On 28 July 1808, Selim was informed by Ahkbar that the Assassins were approaching and was urged to abandon the palace. Although he did not see a good reason to leave, Selim was convinced by Ahkbar to abandon the palace after being told that Assassins would stop at nothing to retrieve the Koh-i-Noor.
However, much to Selim's shock, Akhbar then took the box containing the relic, revealing himself to be an Assassin. Selim asked Ahkbar if he was going to kill him, which prompted Ahkbar to reveal that he had poisoned Selim's tea earlier and that he would be dead soon. As Ahkbar had predicted, Selim died shortly after.
- Historically, Selim III was deposed and imprisoned by the Janissaries in 1807, who then placed his cousin Mustafa on the throne as Mustafa IV. The following year, Selim was killed by a group of assassins in Topkapı Palace on the orders of Mustafa, his last words apparently being "Allahu Akbar" ("God is great").
