Aurelis is a smaller continent to the west of Rodinia accross The Western Seas much of the continent is made up of deep mountain ranges that are difficult to civilize and as such most of the populace reside of archipelagos the reach off the eastern coast of the continent.
Aurelis is also, nominally, a single empire. However it has been in a state of perpetual civil war for at least the last 500 years. The Shogunate of Shogun Heiko claims authority over all citizens of Aurelis, but many of the more powerful noble families refuse to recognize the Shogunate’s authority and have been fighting them for generations. Many of these families control powerful fortifications and as such the Shogunate has never been able to end the war (though it still wins a majority of engagements).
The only contact Aurelis has with Rodinia is through Eralian merchants trading with the shogunate. This trade is prominently cultural, but also in metals (Eralian Gold and Silver, for Aurelian Steel).
