Military action
The Bürach Empire started a war against the Ostoyan people as they refused their claim to the land of Ostoya.
After spending two hundred years taming its borders, the Bürach Empire turned its attention towards expansion. Since the Ostoyans were descended from the Bürach, the Empire deemed them its citizens, ordering them to pay taxes and turn over control of their mines. When the Ostoyans refused, the Bürach attacked. The Ostoyans hastily forged their arms and mustered their men. The wealth drawn from their mines allowed them to bolster their army with mercenaries such as the Free Swords. Despite this, the Ostoyans were not adept at war, having lived too many years in peace. Were it not for the natural borders of their forests and the Grey Spine, Ostoya would have been overrun long ago. Still, the Bürach gained a firm foothold in the region.
