1st Era (jan 1, 431 BC – jan 1, 0)
Human Colonies ruled by the Gewo Empire in Gewos
They consolidated the continent through treaties, alliances, and conquest over the prior 300 years and the height of the empire lasted another half a century before some calamity back home cut off all ties with the mainland, and a hostile invasion from western overseas raiders shut down travel to the mainland.
