The Adepta Sororitas train rigorously and fight with ferocious zeal, pious serenity, and tireless skill. These devout warriors annihilate heretical cults, xenos, mutants, and the abominations of daemonkind as they spread the light of the God-Emperor with fury and flame.

Resplendent in gleaming gold, the Adeptus Custodes stride into war with the confidence earned through ten millennia of martial superiority. Bullets and shrapnel ricochet from gilded auramite breastplates – these warriors are armoured with the finest wargear, carrying the blessing of the God-Emperor Himself. When combined with the peerless anti-psychic protection provided by the Sisters of Silence, there are few in the galaxy who can withstand them.

The Adeptus Mechanicus are the undisputed masters of Mankind’s technological secrets, many examples of which date back thousands of years before the birth of the Imperium.

The Aeldari once ruled the galaxy, before their civilisation collapsed beneath the weight of its own hedonism. Now the Asuryani sail the stars aboard massive vessels called craftworlds, their citizens keeping to highly disciplined Paths to avoid drowning in the same decadent madness as their ancestors. Each craftworld's Guardians take up arms to defend their dying race, wielding deadly shuriken catapults or power blades, or shredding foes atop their swift Windrider jetbikes.

The Astra Militarum are the backbone of the Imperium's largest armies. They are the men and women who hold the line, a bulwark standing between Humanity and a nightmarish galaxy of horrors. Amongst the Astra Militarum's massed regiments, the born soldiers of Cadia are some of the most disciplined warriors to be found – tough marksmen trained for a lifetime of grim duty.

The Black Templars are the Adeptus Astartes' most zealous Chapter, charging into battle to meet their foes face-to-face and deliver the Emperor's justice at the point of a sword.

The Blood Angels exemplify the image of the Angels of Death more so than any other Space Marines Chapter.

The daemonic servants of Khorne spill from the madness of the warp to corrupt and slaughter, the very battlefield contorting at the touch of Chaos. Gore-drenched Bloodletters hack heads from shoulders, led into the material plane by Bloodmasters, the greatest of their ravenous kind. Mounted atop the infernal engine-beasts known as Juggernauts, a charge by merciless Bloodcrushers breaks the most stalwart resistance, while tireless Flesh Hounds pursue any who flee across time and space.

For ten thousand years, the Chaos Space Marines have waged near-constant war on the galaxy that cast them out. Once the defenders of humanity, the Heretic Astartes have pledged themselves to the Dark Gods. Led by maniacal leaders such as the fanatical Dark Apostle, bitter warbands of Chaos Space Marines roam the battlefield, armed with an array of vicious weapons. Barricades and defenders alike are torn asunder by the devastating heavy armaments wielded by Havocs – and the frenzied swipes of a lumbering Helbrute.

The Dark Angels are a dour brotherhood, characterised by their deep commitment to millennia-old rituals, loyalty, discipline, and self-sufficiency.

The Death Guard are the greatest champions of the Plague God, Grandfather Nurgle, his favoured spreaders of his bounteous gifts.

The Deathwatch are a widespread Chapter of Space Marines and the Imperium's greatest weapon against the manifold threats posed by countless xenos races.
