Dominion ghosts epitomize the height of terran evolution and physical conditioning. Augmented by technologies that harness their innate psionic potential, these lethal operatives use telepathy and other superhuman powers to isolate and destroy the enemies of the Dominion. But when the hunters become the hunted and ghosts start disappearing without a trace, even the most dangerous human soldiers in the Koprulu sector have something to fear... Enter Nova Terra, a ghost of unparalleled ability. On orders from emperor Arcturus Mengsk, Nova embarks on a secret mission to find her missing comrades. As her investigation leads down a maze of dark corridors, painful memories of her pre-ghost years begin to surface. Soon, Nova learns that there might be a connection between the missing agents and her past, a discovery that will pit her against both the shadows of her youth and a terrifying new breed of psionic warrior: spectres.
