Editing Altaïr Ibn-La'Ahad (section)

==Legacy==
Shortly after fleeing Masyaf, Niccolò and Maffeo Polo lost Altaïr's Codex during a Mongol attack, but they eventually reached Constantinople. There, they hid Altaïr's five Memory Seals and began establishing Assassin Guilds, following Altaïr's instructions to ensure the Order's survival in secrecy. Niccolò later completed his journal, titled ''The Secret Crusade'', which became the most detailed record of Altaïr's life.

Despite several attempts to recover the Codex, it was eventually retrieved by Niccolò's son, Marco Polo, from Kublai Khan. Marco passed the Codex to the Assassin Dante Alighieri, who was tasked with transporting it to Spain. Dante was killed by Templars before he could complete his mission, and his apprentice, Domenico, took over the responsibility. After losing his wife Isabetta to pirates hired by the Templars, Domenico decided to disassemble the Codex and hide its pages for safekeeping.

Domenico and his son Renato adopted the name Auditore and built the Villa Auditore in Monteriggioni. Beneath it, they created the Sanctuary to store Altaïr's unbreakable armor, which later came into the possession of Domenico's descendant, [[Ezio Auditore da Firenze|Ezio Auditore]]. However, the armor was destroyed during the Borgia attack on the Villa Auditore in 1500.

Ezio also recovered the scattered pages of Altaïr's Codex, using them to create weapons with Leonardo da Vinci's help and to locate the hidden Vatican Vault. Later, through a letter from his late father, Ezio learned of Altaïr's library and traveled to Masyaf. There, he retrieved Niccolò Polo's journal from a group of Templars who sought the library, believing it would lead them to the Grand Temple.

From the journal, Ezio learned of the five Memory Seals hidden in Constantinople by the Polos and set out to find them before the Templars could. As he recovered each seal, he relived Altaïr's memories encoded into them, though the full message Altaïr intended to convey was not immediately clear. Eventually, Ezio accessed the Masyaf library and found Altaïr's skeleton holding the sixth and final Memory Seal.

After reliving Altaïr's final moments, Ezio understood that Altaïr had sought to warn him about the suffering caused by his obsession with knowledge. Determined not to make the same mistake, Ezio chose to leave Altaïr's Apple in the library, stating he had "seen enough for his life." Recognizing his role as a messenger for his and Altaïr's descendant, Desmond Miles, Ezio felt he had fulfilled his purpose and decided to retire from his life as an Assassin. Altaïr's Apple was later removed from the library and came into the possession of Queen Elizabeth I of England.

In 1722, [[Edward Kenway]] offered his hideout in Great Inagua as a replacement for the Assassins' compromised base in Tulum. Ah Tabai, the Mentor of the West Indies Assassins, accepted the offer and suggested that, over time, the Brotherhood should decentralize and live among the people they sought to protect, following Altaïr's earlier advice.

In 1791, the actions of Altaïr were used by the fanatical Master Assassin Pierre Bellec to justify his actions in poisoning Mentor Mirabeau. Bellec cited Altaïr's and other Assassins' achievements to support his goal of destroying and then rebuilding the French Assassins stronger than before.

By 1862, British Assassin [[Evie Frye]] studied the chronicles of Altaïr, as well as other legendary Assassins like Ezio Auditore and Edward Kenway. These stories inspired her to seek the knowledge contained within the Pieces of Eden.

In 2012, the Templar organization Abstergo Industries kidnapped Desmond Miles, known as "Subject 17," and forced him to relive Altaïr's genetic memories in the Animus Project. Their goal was to find a map indicating the locations of Pieces of Eden, but the process also unlocked Desmond's dormant Eagle Vision, revealing hidden messages from Subject 16.

After escaping Abstergo, Desmond experienced the Bleeding Effect and relived a memory of Altaïr outside the Animus. This memory, in which Altaïr chased a hooded figure revealed to be [[Maria Thorpe|Maria]], allowed Desmond to witness the conception of his ancestor, Sef Ibn-La'Ahad.

In a comatose state, Desmond was placed in the Animus 2.03 to repair his fractured subconscious. During this period, he sought a memory linking himself, Altaïr, and Ezio. The Apple of Eden and Ezio's acknowledgment of the future in the Masyaf library enabled Desmond to enter a Synch Nexus and learn the Grand Temple's location from Jupiter of the First Civilization.

In 2013, following Desmond's sacrifice to protect Earth, Abstergo Entertainment considered using Altaïr's memories for their virtual features, aiming to promote him as a positive role model. However, market analysts deemed Altaïr unsuitable and preferred Abbas Sofian instead. Despite this, CCO Melanie Lemay later suggested Altaïr's memories could be valuable for a series on notable historical serial killers.

By 2016, Altaïr's sword was on display at Abstergo Industries' Madrid facility. The following year, Master Templar [[Juhani Otso Berg]] relived Altaïr's memories at Abstergo Montreal to incorporate Altaïr's skills and knowledge into his role as the Black Cross.

Altaïr is remembered as one of the most influential Mentors of the Assassin Order, with his impact still felt in the modern age.
