Four World Powers (270 A.D.A.)

The Four World Powers (270 A.D.A.) are the four global powers of that period:

1. Sileos (Han Empire), in the far East: stable and powerful.
2. Axum, in Africa: a significant power.
3. The Roman Empire: fragmented (Crisis of the Third Century, co-emperors Valerian and Gallienus).
4. The Persian (Sasanian) Empire: the historical eastern rival of Rome.

The arrangement parallels the geopolitics of Antiterra in 1888 A.D.A.: England dominant, a demonic East and Atlantis hidden in Africa.
