==History==
===Middle Ages===
In 1257, Niccolò and his brother Maffeo Polo were invited to stay at the Assassin Order's fortress of Masyaf in Syria. Having been visited by Altaïr Ibn-La'Ahad's son Darim in their home in Constantinople, they journeyed to Masyaf, where Niccolò had various discussions with Altaïr about the latter's life. As a result, Niccolò wrote these stories down in a journal, which ended up covering all of the Assassin's key moments. Niccolò also wrote about Altaïr's library hidden in Masyaf.Assassin's Creed: The Secret Crusade 
The journal also acted as a sort of diary, giving details of the Polo brothers' actions during their stay in the village and their travel to Constantinople where they hid the keys of Altaïr's library. Niccolò intended to pass the journal to his son, Marco.
===Renaissance===
During the late 15th century, the journal had come in the possession of the exiled Ottoman prince Cem, a Templar who was imprisoned in Europe. Shortly before being killed by the Italian Assassins in February 1495, Cem notified of its existence to his nephew Ahmet, heir of the Ottoman throne and Grand Master of the Byzantine Rite of the Templar Order.Assassin's Creed: Recollection
In 1495, the journal fell into the hands of the Spanish Inquisition. Not understanding its true value, they were prepared to trade it to agents of the Byzantine Templars. Through a Templar turncoat, Aleksei Zima, the Ottoman Brotherhood of Assassins learned of these plans. He, along with the Ottoman Mentor Ishak Pasha, the mentor’s bodyguard Murat Bin Husn, and the Assassin Yusuf Tazim, traveled to Spain and cooperated with their Spanish brethren to thwart the deal. However the trade, which had already taken place, was a trap and the Assassins were forced to escape from an ambush.Assassin's Creed: Rebellion – The Ottoman Connection
With the journal, Ahmet learned more about Altaïr's library and wanted to open it to find the Grand Temple to unify humankind by destroying all division.Assassin's Creed: Revelations - Discovery By 1509, after discovering one of Masyaf's keys, Ahmet passed the journal to the Byzantine captain Leandros who headed an expedition to Masyaf's fortress.Assassin's Creed: Revelations - A Journal of Some Kind He kept the journal until March 1511, when he was killed by the Italian Mentor Ezio Auditore da Firenze who was on a quest to enter the library as well.Assassin's Creed: Revelations - The Wounded Eagle
Learning that the keys of Altaïr's library were located in Constantinople after reading the journal, Auditore set out on a journey to the city, while continuing to read the journal along the way. Arriving two months later, the Mentor met Yusuf Tazim who was then the leader of the Ottoman Assassins. During a discussion, Auditore showed the journal to Tazim.Assassin's Creed: Revelations - Bomb Crafting
