The Sabbat War is a savage Imperial crusade, cutting a bloody, burning path across a vast swathe of the Imperium's lost territory. On the front line, the stalwart regiments of the Astra Militarum, including the valiant Tanith First-and-Only—better known as Gaunt’s Ghosts—confront the relentless menace of Chaos, the Archenemy of Mankind. There is, and ever will be, only war.

In the ruined border town of Vincula, the newly formed Tanith First and Only and their commander, Colonel-Commissar Ibram Gaunt, are assigned to enforce a permanent peace. However, this thankless police action will prove as dangerous as any frontline—something is stalking the Ghosts through the streets, and soon the Tanith First will learn dark secrets about themselves that will echo through their history.

An Imperial general has defected to the enemy, and the secrets he carries could spell the end of the Sabbat Worlds Crusade.

Their mission: to stop the traitor general from revealing his secrets - by any means necessary.

When Colonel Haskell 'Hell Fist' Aldalon and the Catachan 57th Jungle Fighters arrive on the quagmire world of Gondwa VI, they find it locked in the grip of an ever-growing greenskin threat.

In the process, they are saddled with the sole survivor of the outpost's fall—the barely trained Trooper Torvin, of the Skadi Second Infantry.

Imperial commissar Ciaphas Cain returns to Nusquam Fundumentibus to crush the ork attacks which have been plaguing the frozen planet.

The grand halls of Fenris grow ever quieter in the wake of the Space Wolves' arduous campaigns. Concerned by his Chapter’s diminishing numbers, the Great Wolf Logan Grimnar entrusts Njal Stormcaller with a task - to find a remedy for their plight.
