The Great Exodus was a period when vast numbers of people migrated from Gulimbor and border areas of the Azrik region. The refugees of these regions fled from either the First Khazarkar Empire and or the havoc wrought by a magical cataclysm that came out of the Domination Wars(995 - 1016). During these wars, the reckless use of magic, prolonged over years, resulted in tears in the Web of Magic. This brought on the Gulimbor Cataclysm(996 - 1203), driving five nations to relocate. The lands they left behind in the Great Exodus, Gulimbor and the upper northeastern edge of Azrik, became virtually uninhabitable.
The Cal-Thaoun Dynasty, the Burterinii, and the
Niratar Theocracy went to Hells Womb, Ma'Ohari, and the Lands of Purity, respectively. The Melephaeusans resettled on the Isle of Gathrot, the largest of those that would become known as Necrocrypt. As for the people of the Borillisk Empire, they went west joining the Ba'lith Empire or far north to Sahuld, another of Necrocrypt's isles that would prove the end of those that settled there. The First Khazarkar Empire, the empire that started all of this, was the last to abandon their homes and conquered lands. They went even further north than all the rest, settling on the far eastern coasts of Cinazan.
The migration of such large populations required herculean efforts by the people. Logistics, ships, food, water, and the necessary supplies for establishing new settlements were planned over years. Countless ships were manufactured, where not a tree stood for many miles around towns and cities. Crossing the seas did not go without trial. Tens of thousands were lost to storms, pirates, and predators from the deeps.
