In 259, Cuervo journeyed to Gaul to meet with Accipiter, an Aleman Assassin. Aware of the Alemanni's desire to conquer Lugdunum, the capital of Gaul, Cuervo warned Accipiter that looting the city would harm the Assassin Brotherhood based there.
To meet the interests of both the Alemanni and the Assassins, Cuervo arranged a meeting between the Prefect of Lugdunum and Accipiter, in which the latter would request a sum of gold from the Prefect, to which the Alemanni would not ransack Gaul's capital.
- Cuervo is a Spanish word meaning "crow, raven". However, Spanish is a Romance language that evolved from spoken Latin and emerged much later than the 3rd century CE.
