The emperor Valens was another one of Rome's finest leaders. Under his reign, the Viking threat made itself known to the world and, just as quickly, steps were taken to hold them off. More importantly, the advances in technology that Archaedavincus had been bringing the Romans for the previous 40 years were fully integrated into the functioning of the Empire. Finally, Valens made the greatest administrative reform of the Empire since the IVth Century, changing the very way that its vast area was governed.
