Era beginning/end
Also known as the Great Purge.
The tribal groups of Humans started to march across all corners of Etharis, catching the kingdoms of the Elves and Dwarves off guard. Their territory was usurped, making the humans the dominant species across the land. Those that resisted were dismantled or pushed from their, while those who didn't were simply assimilated. This Era of Expansion was only halted by conflicts within their own ranks.
