The diverse histories of Cipangu and Magellania are generally grouped into four categories. Prehistory, antiquity, the classical period and the colonial period. The classical period is marked by the early contact with East Asia, while the colonial period begins with the Magellanian discovery.
The prehistory of Cipangu and Magellania contains all the great migrations of the main ethnic groups of both continents. This includes the Proto-Magellanians, the Cipanguans and the Austronesians, as the latest of them.
Ancient history begins with the advent of agriculture on Magellania and the transition towards and urban culture on both continents. The end of antiquity sees the rise of the Atmurene Empire as the first empire in the north and the beginning of the great thalassocracies in the intercontinental zone between both continents.
The classical period begins roughly with the first contact with the East Asian mainland and the sinosphere cultural area. The early Classic seas a continuation of a declining Atmurene Empire and the heyday of the thalassocracies. In the 730s a devastating small pox epidemic hits Cipangu and destroys both the Atmurenes and the thalassocracies, effectively isolating both continents from each other. The rest of the Classic has both cultural zones continuing in parallel in isolation from each other.
The colonial period begins with the discovery of Ferdinand Magellan. It seems the colonization of most of Cipangu and Magellania by various European powers, as well as the resistance and rise of strong native states. During this time both continents become increasingly well connected to the rest of the world.
The most current year is the year 1890. Most European powers have established a foothold on Cipangu and Magellania. However there are also powerful Cipanguan and Magellanian states. In the far north, Zhughaw has successfully modernized and become a power on par with neighboring European colonizers.
In the south the Empire of Saokaŋ has resisted both Spanish and Dutch encroachment and aims to expand onto the continent in its own right.
The divergences of history have created a different world. One where the 1860s saw the first great war and where familiar players have received an unfamiliar face.
