The history of the Neville Federation is considerably long, it can be traced back to the reign of the Zeras Empire which existed around 2500 years ago. The Zeras Empire dominated the present lands of the Neville Federation, the Neutral Land, and a portion of the Falar Empire territory. When the Zeras Empire's interior collapsed, parts of the land were taken up by the predecessors of the Falar Empire, the Neutral Land was turned into a buffer zone, and the main theme of the Zeras Empire split into nineteen unequally sized mini-empires.
After several millennia, these nineteen small nations underwent countless conspiracies and chaos, constantly collapsing and being rebuilt. Yet they remained divided. Finally, 500 years ago, their incessant encroachment on the Beastmen Prairie led to the transformative War of Man and Beast.
