The Drukhari city of Commorragh is without question one of the worst places in the universe - giving even the warp a run for its money - and those who thrive in its dark and treacherous streets are brought up on a diet of murder, intrigue, and more murder. This urban hellscape is what created Lelith Hesperax - the deadliest gladiator in the galaxy, and the slayer of countless souls on the grim blood sands of the Dark City's arenas.

In the darkest corners of the webway lies the city of Commorragh. Home to the sadistic drukhari, millions are butchered upon its arenas' sands to slake their terrible thirst for blood.

Greatest of these butchers is Lelith Hesperax, the Queen of Knives, deadliest gladiator in the galaxy. But she has abandoned the Dark City to walk alongside the nomadic death cultists of the Ynnead, and in her absence rise pretenders to her blood-soaked crown.

When a blade strikes at Lelith from the shadows, she is dragged back to Commorragh and into the murderous games of the Living Muse himself - Asdrubael Vect. As his schemes coil around her, the Queen of Knives finds herself ensnared once more in Vect's terrible web, and this time her blades may not be enough to free her...
