Charlemagne (Latin: Carolus Magnus; 742 – 814), also known as Charles the Great or Charles I was the King of the Franks from 768, the King of Lombards from 774, and from 800 the Emperor of the Carolingian Empire, which would eventually be succeeded by the Holy Roman Empire. He was also a leader of the Order of the Ancients.
In May 804, Charlemagne was written a letter by Alcuin regarding the existence of the Order of the Ancients and how they were a parasitic group neglecting God's teaching and instead worshipping a race of precursor beings known as the Isu. Alcuin also informed Charlemagne about the Order's obsession with sages, Isu allegedly reborn as humans. Believing the Order to be blasphemers, Alcuin was unaware that Charlemagne himself was a member of said order. Despite being a pious defender of God's will, Charlemagne hid his allegiance well. The Order then had Alcuin killed a week later as he knew too much and his letter was never sent.
In 2012, Charlemagne was one of many historical people included in the Glyph puzzles the late Assassin Clay Kaczmarek had left behind in the Animus as messages for his successor Desmond Miles to decipher. Desmond later did in September of that year. Desmond solved this puzzle, which was part of a set titled "Instruments of Power" where Charlemagne was excluded from the list of historical individuals revealed by Clay to have wielded a Sword of Eden. In the same year, he was included in a mnemonic set in Abstergo Industries' Project Legacy.
In 2020, during Layla Hassan's Animus session of reliving the memories of the shieldmaiden Eivor Varinsdottir of the Raven Clan during the Viking expansion into England, a set of armor inspired by Charlemagne was made available to her through an Animus modification.
