Lore24 - The Sovereignty - Exodus

According to knowledgeable sages, humanity has had a presence in the lands that would become the Sovereignty even before the mass immigration called "the Exodus" took place. Forlorn ruins and excavated tribal remains testify to that notion. But the biggest proof was the presence of the City of Dawn, Aurora, itself.

Before the Exodus, humans were native to the eastern, paradisical, lands, whose original designation have been lost to time and catastrophe. In this paradise, they were shepherded and tutored by the High Elves of that land. The human tribes learned language, culture, invention and even magic from the elves. In time, the inventive folk of humankind struck out on their own, beyond the shores of paradise, to lands over the horizon. It was a clan of these enterprising humans that founded Aurora as the first human city, a colony in the western lands. 

When magical cataclysm befell the eastern paradisical lands, causing them to become "the Lost Lands", humans of all stripe and color, as well as remaining elves, fled westward to these shores. And while most of the elves settled on the island of Lendor, humanity fled to the bastions of Aurora. From there, groups of like-minded humans struck out into the wilderness, to take land, cultivate food and rebuild civilization. Peoples of all ethnicities flocked together, causing the new cultures of the Sovereignty to become a mix of different clans and populations. Intermarriage between clans and, later on, kingdoms, became common, meaning that the Sovereignty is a true melting pot of creeds and colors. 

What caused the cataclysm is a topic of debate among the wise. Some say it was ecological collapse, a freak natural accident that destroyed the life-giving properties of paradise. Others, more suspicious, say the High Elves cast humanity out, out of fear of their pupils surpassing them in magic and invention. A select few point to the current happenings in the lands of the Sovereignty, the rise of Beastmen and monsters, and say that the Mother of Monsters herself rose up against elves and humans. And other select sages suggest it was all the work of magical experiments of epic proportions - rains of colorless fire, devastating invocations - gone awry.

Whatever the cause, the catastrophe was sudden, the ruin utter. The eastern continent became uninhabitable for both elves and humans. And thus, the Exodus.
