The Nomadic Empires were formed during the chaotic era spanning thousands of years between The Sixty Minute War and the Traction Era. These empires were nomadic due to the instability of the Earth caused by the use of powerful weapons by the Ancients during The War. Notable Nomadic Empires mentioned in the series include The New Roman Empire, The Anglish Empire and The New Mongol Horde.
They were followed by the Nomad Empires.
