Top 10 Dominant Factions in the Warhammer 40k Universe
The Warhammer 40,000 universe is home to a dark future filled with war, horror, and struggle. Many powerful factions fight ruthlessly for domination and survival, but a select few stand clearly above the rest in terms of their influence and threat level. After exhaustive research into the lore and crunch behind these mighty forces, I‘ve compiled this definitive ranking of the 10 most dominant factions in 40k.
-
Adeptus Mechanicus
As keepers of technology for the Imperium of Man, the Adeptus Mechanicus control production, innovation, and key war materiel for humanity‘s ongoing wars. They are desperately reliant on ancient Standard Template Construct machine spirits for all processing power and are philosophically opposed to true invention, stifling innovation. However, they maintain a stranglehold on existing technology and manufacture the Imperium‘s arsenal. Without the Techpriests of Mars, the Imperium would collapse overnight. -
T‘au Empire
The T‘au are the youngest race in 40k, having developed interstellar travel capability only within the last 10,000 years. But guided by their philosophy of the "Greater Good," T‘au technology has developed at supernatural speeds. Through diplomacy, commerce, and conquest, their empire expands its sphere of influence every standard year. They lack the raw numbers of other factions but more than make up for it in mobility and coordination. The stubborn optimism of the T‘au endures, even in the grimdark 41st millennium. -
Forces of Chaos
The warp-born powers of Chaos unite behind ultimate destruction of realspace but little else. Khorne, Tzeentch, Nurgle and Slannesh have infinite daemonic legions to throw into the materium, united only by their metaphysical need to wreak havoc. Cult uprisings and traitorous defections gives Chaos clandestine but unreliable human troops as well. Trillions of bloodthirsty daemons and zealots fight for Chaos but are eternally fractured by rivalry and scheming. -
Tyranid Hive Fleets
The extragalactic Tyranid collective consciousness has traveled through the void between galaxies to feast on the Milky Way. With no signs of individual thought, personal glory or internal strife, Tyranids act in perfect concert towards the singular goal of consumption and reproduction. Biomorphs are evolved to counter threats and consume bio-matter more efficiently, however the true danger comes from countless hive ships remaining undiscovered in space, slowly moving to take worlds by endless surprise swarm attacks. -
Necrons
Eons ago the Necron race shed their mortal flesh in favor of metal forms and became all but immortal. After 60 million years of slumber they awake to reestablish their dynasties and harvest inferior lifeforms for fuel. Necrons make up for relatively low numbers with near indestructibility and vastly advanced weaponry. Consciousness caste members seek to have their essences transferred into the flesh bodies of younger races who still retain the gift of death, but at the cost of disunity. -
Asuryani Craftworld Eldar
The remains of the once dominant Eldar empire now cling to survival aboard continent-size worldships drifting through space. Their race devastated by psychic cataclysm in ages past, each Craftworld guards the lives of the last remnants of their species. Webway portals allow the Eldar to strike across vast interstellar distances with unmatched mobility. The warrior Aspect Shrines demonstrate elite psychic might and combat discipline. But conflicting seer visions guiding each craftworld foster divisions that leave them isolated and vulnerable. -
Orks
Orks infest worlds via fungaloid spores that grow into a deadly ecology filling their barbaric needs for warfare. Being innately drawn to combat by the echoed psychic emanations of fellow Orks, fractious klanz unite as massive WAAAGH! crusades that swarm across the stars. With physiology lending itself to developing muscle over mind, Orks rely on odd belief-based technology as much as anatomy. So long as two spores land after a WAAAGH! passes, the Ork ecosystem thrives in death and destruction. -
Forces of Chaos (United)
When the Chaos Gods fully unite to marshal the Archenemy towards a single purpose, their power grows tenfold. Daemon Primarchs and mortal Chaos Champions alike drive the massed Traitor Legions and heretic Astra Militarum regiments forward. Possession, sorcery and the corrupting influence of warp exposure shatters the resolve of loyalist forces. By cosmic foul luck should the Dark Gods put aside their Great Game for but a moment, no single power could hope to stand against their might. -
Imperium of Man
Trillions of humans scattered across the galaxy fighting together for the survival of their very species fuels the manpower behind the Imperium’s grinding war machine. The High Lords on Terra bend regional governors to supply fresh conscripts that fill the ranks of the Astra Militarum. Ancient maimed heroes interred into Dreadnought walkers lead the Space Marine Chapters in righteous fury. The Imperial Cult binds humanity in faith of the Emperor and hatred of aliens and heretics. Unyielding and uncaring sacrifice in war steels mankind’s grim last stand. -
Tyranid Hive Fleets (Galactic Threat)
Slowly the tendrils of Hive Fleets snake towards Terra, consuming worlds and swelling the biomass of the Tyranid titan consciousness. Each tendril seen so far comprises only a splinter of the full Tyranid race still approaching from dark intergalactic space. Genestealer Patriarchs establish cults that infest worlds long before fleets arrive, sowing chaos to cripple defenses. As more Tyranid Hive Fleets emerge in full and consumable galaxy sectors dwindle, their threat overshadows all others. Once awakened to our galaxy’s feast, the Great Devourer will not stop until all life is Tyranid.
The grim darkness of the far future leaves little hope, as malignant forces like Thirsting Gods, Crawling Chaos and Starvation encircle the last survivalist enclaves of living beings. But determination against inverted sanity and parasitism perseveres, as it must for any who accept that they will live and die under martial law. The fate of each dominant faction wrestling to determine the destiny for the inhabitants of the Milky Way lies poised on an Azyr’s Edge.
