The Great Migration was a monumental event in the history of Eredonia, triggered by the rapid expansion of the Roman Empire in the east. The conquests and subsequent rule of the Romans, who harbored a disdain for non-human races, forced tens of thousands of beings from diverse races to migrate westward in search of safety and freedom. This mass movement was characterized by the upheaval of entire communities, as people sought refuge from the oppressive rule of the Roman Empire. Aelvari, Delverkin, Hearthkin, Gnomes, and various other non-human races found themselves compelled to abandon their ancestral homes and embark on arduous journeys to the western regions of Eredonia.
