Prophecy of Cora
The Cerune Empire was once the dominating force in the Bordermarches. Having sailed across the seas from another continent (the name of which I forget but need to add), they established a presence in the bay of Raentallas 1,200 years earlier. They built the city of Mirelenai on the bay, and then began their exploration of the continent. Through their impressive force, they were able to convince existing settlements like Bran Modran, Calmen and Khordun to align with them. Over the next two hundred years, the Cerunae established three more major cities in the realm: Aulivar, Lanaloth, and Aelwyn. Technically, the Empire did not establish Aelwyn; they conquered it from an indigenous human nation which was driven off into the east.
At that time, the Empire across the sea began encountering a number of problems which diverted attention and resources away from expansion. Expeditions had already determined that the frozen region to the north and the desert to the southeast were considered inhospitable, and the Tiernalen expedition into the east was completely destroyed. For that reason, expansion in the region came to a halt. The Cerunae established a line of watch towers across the realm, enabling signalling between the towers in the event of an attack.
The decline of the Empire continued, and support from across the sea became minimal. The last Cerunae-appointed Governor of the Bordermarches, Magistrate Trellevis Alathon, was assassinated 325 years ago. After that, there was no contact from the Empire. The nobles in charge of each of the cities met in the Governor’s Palace 300 years ago, and there decided that each city should rule their own affairs. They became city-states in a loose alliance with each other, friendly rivals for what power and resources still remained in the realm.
