|A map of the Romanum 01 universe in 2014|
The Romanum universes are alternate histories which involve the circumstances of the Roman Empire's collapse never occurring.
A slightly different version of Romanum 01, where Rome was always a Kingdom that has, as of 2013, been ruled by the House of Caesar for over a thousand years.
A universe where the Roman Empire was always controlled in Constantinople (Byzantium in the Romanum 03 universe, and in the past of the real world) and always was the Byzantine Empire
A universe like the Romanum 01 universe, except that the Greeks overthrew the Romans in the 15th century and formed a separate, united empire. While the Romans tried to reconquer them, their forces were divided too thin to keep the other states under control and a civil war occurred, leading to Rome losing most of it's territory and military power. The Norse people became a major power in this world, forming the Scandinavian Empire.
A mirror universe to Romanum 01, where there was a different chain of events following the Romano-Xanj Incident. Instead of a peaceful first contact, Rome invaded and eventually conquered the Xanj people, using their advanced technology to take over the world, forming the Latino Terranic Imperium.
