Memory Seals
Memory Seals were First Civilization artifacts with the ability to contain recorded memories. They were said to be the technological basis of the Animus device of Abstergo Industries.
History
Altaïr's library
In his late life, Altair Ibn-La'Ahad, Mentor of the Levantine Assassins, came upon six memory seals. He used each of them to record an important event in his life, while five were needed to enter his library, which was hidden beneath the Assassins' fortress of Masyaf.
Upon Altaïr's request, Niccolò Polo took the five memory seals, and hid them in small tombs throughout Constantinople. Respectively, the seals were placed within Topkapı Palace, the Yerebatan Cistern, Galata Tower, the Forum of the Ox, and the Maiden's Tower. The sixth memory seal remained with Altaïr inside his library, where he recorded his final moments.
In around 1512, Ezio Auditore da Firenze uncovered four of the seals, gained the final one from Templars in Derinkuyu, and found the final one upon entering Altaïr's library.
Library of Alexandria
Two memory seals in Alexandria were located by the Mamluk Sultan's soldiers in 1511, during the excavation of the Library of Alexandria. These seals, kept within a chest dated 331 BC, were recovered by the Egyptian and Ottoman Assassins shortly afterwards.
These two seals from Alexandria were later taken to the local Assassins' headquarters, where they were studied by an unidentified woman referred to as a "blessed initiate." As she worked to "unlock the mysteries" of the seals, the Templars led an attack on the headquarters, though they were thwarted again by the Ottoman Assassins.
