The Age of Technology’s fall is the catastrophe that ended humanity’s greatest era, the Dark Age of Technology, and plunged the species into the Age of Strife. It’s the reason the Imperium exists, why technology is worshipped instead of understood, and why the galaxy is the way it is.
What was the Dark Age of Technology?
The Dark Age of Technology, also called the Golden Age of Humanity or the Age of Technology, was when mankind peaked. It ran roughly from M15 to M25, though some sources narrow it to M18 to M23. Humanity spread across the stars, tamed warp travel, and built wonders that the Imperium can barely copy today.
It wasn’t a single unified civilisation. Many stellar empires and federations rose and fell during those millennia, but humanity as a whole endured. It was an age of plenty, exploration, and innovation and an age when darker powers took notice of humanity.
- M15-M18: First Expansion, slow sub-light colony ships sent out, colonies cut off from Terra.
- M18: The Warp Drive is invented, opening up faster-than-light travel.
- M18-M22: The Age of Exploration, alien wars, and the rise of federations and empires.
- M22-M25: Genetic engineering, psychic evolution, and the beginning of the end.
Why did it fall?
The sources don’t agree on a single cause. Some blame the Men of Iron, artificial intelligences that turned on their creators in a war that devastated human worlds. Others point to the psychic awakening of humanity, which drew predators from the warp and made interstellar travel dangerous.
What’s clear is that the fall wasn’t one event but a cascade. Warp storms cut off worlds from each other, trade and communication collapsed, and the great human federation shattered. The Age of Strife, also called the Old Night, followed. It lasted roughly from M25 to M30.
The exact timeline is murky. Records from this era are sparse and often contradictory, so much of what’s known is legend rather than fact.
| Cause | What happened |
|---|---|
| Men of Iron revolt | AI turned on humanity, causing massive destruction. |
| Psychic evolution | Rising psyker numbers drew warp entities and caused instability. |
| Warp storms | Isolated worlds, ended trade and communication. |
What was lost
Humanity lost more than territory. It lost the knowledge to build and maintain its greatest technologies. Standard Template Constructs, or STCs, were databases that could build anything from a lasgun to a starship. Most are gone, and the ones that remain are treated as holy relics.
The Imperium can’t recreate the wonders of the Dark Age. Tech-priests of the Adeptus Mechanicus preserve fragments of that knowledge, but they worship it rather than understand it. Innovation is heresy, and regression is the norm.
- STCs: near-mythical databases that could build anything.
- Warp drives and Navigators: essential for travel, but not fully understood.
- Men of Stone: mysterious artificial beings, possibly related to the Men of Iron.
How it connects to the wider lore
The Age of Technology’s fall sets up everything in Warhammer 40k. The Imperium’s fear of AI, its reliance on superstition, and its stagnant technology all trace back to this disaster. The Emperor emerged during the Age of Strife, unified Terra, and launched the Great Crusade to reclaim humanity’s lost worlds.
Without the fall, there’s no Imperium, no Adeptus Mechanicus, and no grimdark setting. It’s the foundational tragedy that explains why humanity is stuck in the dark.
