The Sabbat War is a savage Imperial crusade, cutting a bloody, burning path across a vast swathe of the Imperium's lost territory.

There is, and ever will be, only war.

The Great Crusade is ending. The Emperor has returned to Terra, while Horus remains among the stars to complete the unification of humanity. As the Imperial armies fight the final battles of the age, Remembrancer Solomon Voss seeks the answer to one question—why does Sigismund, First Captain of the Imperial Fists and greatest champion of the Legions, believe that war will not end? Granted a rare audience with the master of the Templars, the answer takes Voss on a revelatory journey to a time before Sigismund became a Space Marine.

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.

The Indomitus Crusade continues its war across the stars.

Kor Phaeron, the Dark Cardinal, threatens the previously stable core of the Segmentum Solar. Waves of rebellion instigated by his infiltrating priests suggest an imminent, large-scale invasion by the Word Bearers Legion. 

Of the billions of greenskins who swarm the galaxy, the name of one strikes fear into the hearts of human and xenos alike—Ghazghkull Mag Uruk Thraka. The Warlord of Warlords. The Beast of Armageddon. The Prophet of the Waaagh! With his tusks, fists and power claw, he does the holy work of Gork and Mork—and soon all worlds will burn in his bootprints. Mystery shrouds the origins of such a beast. Rumours abound that the mighty warlord was once just like any other ork—but if that is the case, how did he rise from a lowly lad to the biggest of bosses? 

When the vital forge world of Orestes comes under attack by a legion of Chaos Titans, the planet is forced to appeal for help. The Titans of Legio Invicta, although fresh from combat and in desperate need of refit and repair, respond, committing their own force of war engines to the battle. As the god-machines stride to war, the world trembles, for the devastation they unleash could destroy the very world they have pledged to save.

Ezekyle Abaddon and his warlords strive to bind the newborn Black Legion together under threat of destruction. Now Khayon, as Abaddon's most-trusted assassin, is tasked with ending the threat of Thagus Daravek, the self-proclaimed Lord of Hosts - a rival to the Ezekyle's final fate. Fighting the vile whispers of the Dark Gods within his mind, Abaddon turns a fevered gaze back to the Imperium, where his destiny awaits. Yet the Emperor's Champion and his Black Templars stand guard at the gates of Hell, and Sigismund has waited centuries to face Abaddon in battle.

On the forge world of Morod, the machines never stop and the work never ends.

Genetor Gammat Triskellian seeks to end this stagnant corruption. When he learns of a twisted congregation operating within the shadows, one which believes that the tech-priests are keeping people from their true salvation, he sees in them an opportunity to bring down Morod's masters and reclaim the world in the name of progress.

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.
