Military action
A period of wars that led to the formation of the Golden Empire
The Golden One who mysteriously showed up in a village near a gold mine one day eventually trained them in warfare and began a campaign to conquer all of the human inhabited regions and unite them under one political entity. Starting in the peaceful lands of Agraria, he eventually pushed west to Oasis and the desert, before going north into the Tundra to conquer Snowveil. This eventually culminated in the Silver-Gold War as the Golden One attacked the Silver City. The Conquests are considered to have ended with the coronation of the Golden One in the newly built Golden City.
