A Contest of Nisse and Release
While little is known of the Scarlet Empress before she rose to power, it is known that she was serving as a soldier for the Shogunate of the Realm during what is now known as the Great Contagion. She, along with several other Dragon-Blooded officers, braved the Imperial Manse and used its control of the Realm’s ancient magical defenses to save Creation from the invading Fair Folk. She then crowned herself Empress of the Realm – using her control of the Realm defenses to crush all opposition—and proceeded to rule the world for the next 750+ years.
Her disappearance five years prior to the current timeline of the Exalted universe has upset the status quo of Creation, and the return of the Solar Exalted has only complicated the situation.
