A relic of humanity's violent past, this old weapon stands ready for the Emperor to wield. The Galactic Imperium of the Myriad Worlds slumps into centuries of decadent peace enabled by a flood of advanced technology from the mysterious nonhuman "Shapers." Among the great Families, only the once-mighty clan of Sinclair-Maru remembers the maxims of the warrior Emperor, Yung I, ready to defend the Imperium from any threat. Stubbornly clinging to the Honor Code, Family prodigy Saef Sinclair-Maru finds himself in command of an outmoded, under-equipped frigate of the Imperial Fleet. With spies and assassins on every side, trusting only in his considerable skill and the bizarre competence of his companion, Inga, Saef must complete his mission, restore the greatness of his Family, and uncover the chilling plot meant to extinguish humanity's light from the galaxy.
