Series information from goodreads.com.

The Hokkaran empire conquered every land within their bold reach-- but failed to notice a lurking darkness festering within the people. Now, their border walls begin to crumble, and villages fall to demons swarming out of the forests. On the silver steppes, the remaining tribes of nomadic Qorin retreat and protect their own, having bartered a treaty with the empire, exchanging inheritance through the dynasties. Infamous Qorin warrior Barsalayaa Shefali and a spoiled divine warrior empress, O-Shizuka will save their world and become legends-- or die trying.
