Plot
In a future where mankind is scattered across the stars, the Empire of Valdana is under the control of the Tytania clan, which forged its influence through intimidation and economic might. In the year 446, Tytania dispatches a large fleet to seize a new piece of technology from the city-state of Euriya. Much to everyone's surprise, Euriya decides to resist and wins. Their isolated act of rebellion sets into motion a sequence of events that strains the careful alliances and treaties within the empire as various factions seek to exploit the situation to their own advantage. In the ensuing turmoil, ambitious members of the Tytania nobility begin moving against each other in an effort to settle old grievances and seize control of the clan. What started as an act of rebellion by Euriya, quickly expands into a civil war – with the wealth and power of the empire up for grabs to whoever is bold enough to seize it.
Meanwhile, Fan Hyulick, the man responsible for Euriya's victory, finds himself the target of an imperial manhunt, one he can only escape by continuing to fight an empire that controls entire worlds.
