Lugdunum (modern: Lyon, France) was a city located in the Roman Empire, which was also the capital of the Roman Gaul. The city was the home to a branch of the Assassin Brotherhood, including the Assassins Aquilus and his father Lucius.
When he arrived in Lugdunum, he found his father in good health, and met a family friend, Senator Caïus Fulvus Vultur. Aquilus almost immediately set out to find the person responsible for his betrayal, and so he sought out Faustin. After a brief interrogation, Faustin betrayed his accomplice: Senator Vultur.
When Aquilus arrived at his house once again, he found his father dead and the Ankh stolen. One of the maids told him the senator had fled the city.
Not much later, the Alemanni moved in on Lugdunum, though their leader, Accipiter, was hesitant to plunder the city because of the Assassins' interests. Instead of plundering it, a deal was made with the Prefect of Lugdunum. The city paid a large sum of gold to keep the Alemanni from invading the city, which made an easy victory for the Alemans.
