Amilanius was the founder of the Atlantean Empire, and by consequence its first Divine Sovereign. He was born during the second proto-Atlantean period as a bastard son of Nergal IV, the ruler of the Opweixj tribe-kingdom. After the collapse of the European proto-Atlantean society, he united the broken tribes of the ancient world, and with them he created the Atlantean Empire. Upon his death in 5284 AHB, Amilanius would be succeeded by his son Nergal V.
