The Factions

Nobody makes it out unscathed.

Warhammer 40,000 is a vast, rich setting for heroes, villains and characters who live in the grey.
The following are a beginner’s guide to the forces vying for power, territory, and glory.


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.

Champions and thralls of the Dark Gods, the followers of Chaos 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.

Mankind is not the only race to walk among the stars. Since they first travelled beyond their own star system, Mankind has encountered alien races, most of which have proven hostile.
