Post-Apocalyptic Greyhawk

A great deal of change separates the North America of the 21st Century from the future age of the Free-City of Greyhawk, sitting on the ruins of ancient Chicago. The upheaval around the Anthropocene Thermal Maximum lead to mass migrations and alteration of the landscape. Four emerging peoples would be largely responsible for shaping civilization of the Greyhawk era.

The ancestors of the Bakluni were sea nomads and climate refugees from Asia who had settled on the southern Pacific Coast of North America. Pressure from groups fleeing north from the Tropic of Cancer led their culture in a more warlike direction--and also pushed them both east toward the Rockies and northward.

The Pacific Northwest was the domain of the Suel culture. It evolved in the main from separatist groups with racial supremacist leanings during the fracture of the United States and Canada. An upper-class of "pure-blooded" nobility ruled over a "mixed race" lower class in a feudal society. The inbred ruling class commonly displayed a unique mutation in melanogenesis that led to pigmentless skin and hair, and violet eyes.

The underclass of the Suel was similar (and indeed often derived from) the peoples of diverse ethnic origin that were the primary cultural group from the Rocky Mountains eastward. These were collectively known as the Flan, though they did not initial share any real concept of national identity. Most Flan lived in small, nomadic or semi-nomadic tribes.

The final group, the Oeridians, were a people of less certain origin, but they seem, like the Suel, to be derived from North Americans of European descent, but with genetic markers indicating a significant contribution from Native American ancestry. They were a tribal people known to both the Bakluni and Suel--and employed by them both as mercenaries.
