Ruyusia is one of the three lands that make up Nastros. Little is known about it, aside from what is contained in past legends. It is known that it is under control of the Ruyusian Empire, for which it is named, and is bracketed by the ocean and The Mountains of Darkness. Previous to Ruyusia's rise to power it was controlled by The Alliance, led by the Orders, and previously to that it was controlled by various warlords. This was humanity's original homeland before most of the survivors of The War of Darkness fled east in The Exodus, settling in Lavon and Castron.
Note that my writing is only up to The Dark Crusade, therefore I haven't actually bothered developing this area yet
