Warhammer 40,000

Explore the Factions

Warhammer 40,000 is a vast, rich universe full of epic heroes, monstrous villains and a host of unique characters in between. Here, you’ll learn more about the forces vying for power, territory, and glory across the galaxy.

The Adeptus Astartes, alongside the vast war machine that is the Astra Militarum and other forces of the Imperium, fight with everything at their disposal to defend Mankind and the Emperor’s realm. The forces of the Dark Gods, whether mortal or daemonic, seek dominion by tearing through the veil of reality itself and letting the power of the Warp flood the galaxy. All the while, alien races – from the barbarous Orks to the technologically advanced Tau Empire, from the ancient empire of the Necrons to their nemeses the Aeldari – look to carve out their own future amongst the stars.

Will you fight for duty or vengeance? Will you raise an army for survival or the sheer bloody joy of the kill? With which force will you wage war in the far future?

STEP 1: choose a side


As the favoured champions of the Chaos Gods, the Heretic Astartes are blessed with many gifts. They may have profane boons bestowed upon them which grant unnatural strength and resilience, or horrific weapon-mutations that can peel the flesh from a foe with sickening ease. All manner of hideous creatures dwell within the warp, a hellish, roiling dimension in which the greatest passions and fears of mortal creatures are given terrible form. Acts of monstrous atrocity or foul ritual can weaken the barriers between realms, unleashing the nightmare of a daemonic incursion into realspace. Led by horrifically powerful Greater Daemons and Daemon Princes – mortals who have been granted the gift of Daemonhood – these profane hosts fight alongside bands of Heretic Astartes and crazed cultists.


Over ten thousand years of constant warfare has honed Mankind’s military might, for the galaxy is a hostile place and only by force of arms is the Imperium held together. It is an age of war and only the strong and the ruthless can hope to survive. Out amongst the stars there can be no mercy, no weakness and no respite from the unending war for survival.


Mankind is not the only race to walk among the stars. Since they first travelled beyond their own star system, in the early days of the Age of Technology, Mankind has encountered alien races, most of which have proven hostile. While some xenos exist only on a single planet, other civilisations might occupy a star system and there are a few that are widely spread across the great void of the galaxy. It has never been in Man’s nature to share his worlds with aliens, and bloodshed has ever formed the foundation of empire.
