The Great Plains is the broad expanse of prairie which lies east of the Rocky Mountains of North Amerika.
The southern portion of the Great Plains was nearly depopulated when the Northern Citadel migrated to Europe to fight in the Holy Cross War against the Danish Empire. Later in the early 18th century the Ghost Dance began on the Great Plains during the Ice War as a response the encroachments of the Nisei. At first allies of the Ice, the Ghostdancers then supported the Shawnee Empire and sided against the Krorist faction in the War of the Dragons. The Ghost Dancers emerged as a distinct nation during the civil war in the Shawnee Empire.
