The year is 3525, and the Alliance of Great Clans has kept the colonized worlds united for over 160 years. When a mining colony is destroyed, old rivalries are inflamed that threaten to fracture the Alliance and bring war to all the worlds. Clan Erstallius is blamed for the attack. Arlud Erstallius is determined to prove his clan's innocence. What he discovers is something entirely unexpected. A dark force has emerged who has more power than all the clans combined. Faced with annihilation, Arlud flees on a journey across the inhabited worlds to find the survivors from the destroyed mine, who can help unmask the new enemy, and bring an end to the chaos that threatens to rip the Alliance apart.
