The Ruinous Powers is the collective name for the four Chaos Gods in Warhammer 40k: Khorne, Tzeentch, Nurgle, and Slaanesh. They’re the great enemy of the Imperium, and they’ve been tearing the galaxy apart since the Horus Heresy.
Who are the four Chaos Gods?
Each god rules a different corner of Chaos. Khorne is war and bloodshed. Tzeentch is change, magic, and scheming. Nurgle is decay, disease, and a twisted kind of endurance. Slaanesh is excess, pleasure, and obsession.
They don’t get along. They fight each other as much as they fight the Imperium, and their followers often clash. But when a mortal threatens them all, they’ll put aside their rivalries, usually briefly.
- Khorne: blood, violence, martial honour (of a sort)
- Tzeentch: sorcery, ambition, endless plots
- Nurgle: plagues, despair, unnatural resilience
- Slaanesh: hedonism, perfection, torment
Why they matter in the 41st millennium
The Ruinous Powers are the main reason the Imperium is stuck in a slow collapse. They corrupt everything they touch, from planetary governors to Space Marines, and they’ve turned half the galaxy into a permanent war zone.
The Great Rift, also called the Cicatrix Maledictum, is their biggest recent victory. It split the galaxy in two and let daemons pour into realspace on a scale nobody had seen before.
How they connect to other lore
The Ruinous Powers are tied to the Horus Heresy, when the Warmaster Horus fell to Chaos and nearly destroyed the Imperium. That event shaped everything that came after.
They’re also the source of Chaos Space Marines, daemons, and the Warp itself. If you follow any Chaos faction, you’re dealing with them in some form.
The Ruinous Powers in games
In the Warhammer 40,000 Commander deck, The Ruinous Powers is a preconstructed deck led by Abaddon the Despoiler. It leans into Chaos themes with cards like Bloodthirster, Great Unclean One, and Magnus the Red.
The deck lets you play a mix of Khorne, Tzeentch, Nurgle, and Slaanesh creatures, which is unusual for a single Commander deck. It’s a good starting point if you want to build a Chaos army on the tabletop.
