Night has fallen on the prison world of Zartak. Renegades from the Imperium's dawn stalk the complex, bringing pain and death. But something just as dangerous awaits them: the loyal, but brutal and predatory, Carcharadons.
On the prison world of Zartak, darkness has fallen on arbitrators and inmates alike. The Night Lords have come, and with them the shadow of fear and pain. But they are not the only ones with an interest in Zartak. From the void, running on silent, another fleet emerges. Its warriors are grey-clad and white-faced, and their eyes are as black as the Outer Dark – the savage Carcharodon Astra. As these two packs of ancient, merciless predators stalk the shadows of the prison colony, both seeking a single young inmate with unnatural talents, the corridors run red, and both factions will have to fight tooth and claw to leave Zartak alive.
A darkened prison, a pack of Night Lords and the Imperium's most predatory Space Marines – what more could you want from a story?
