Aquilus was a Gallo-Roman member of the Assassin Brotherhood in Lugdunum, one of the main character of Assassin's Creed - Cycle 1(Comics), and is a distant ancestor to Desmond Miles.
In 259, Aquilus was tasked with the assassination of several high-ranked individuals within the Roman Empire. Having failed to assassinate his third target, General Gracchus, Aquilus met up with his cousin Accipiter – an Aleman and a fellow Assassin – from whom he obtained an ancient artifact known as the "Ankh", formerly held by the Egyptian goddess Isis.
After his father was murdered and the Ankh was stolen by the Roman Senator Caïus Fulvus Vultur, Aquilus traveled from Lugdunum to the Empire's capital of Rome, seeking vengeance. Successful in his objective, he returned home with the artifact, discovering more of its abilities. Eventually, Aquilus was executed by Roman soldiers.
