Warhammer 40000 Codex

Necrons

The dead rise in iron silence to reclaim a galaxy that forgot them.

The Necrons are not merely machines; they are the ghostly echoes of a once-mortal race, the Necrontyr, whose desperate pact with the star-eating C'tan traded their flesh for living metal. For six million years, they slumbered as cold, skeletal sentinels within tomb worlds scattered across the void, waiting out an age dominated by younger races. Now, the long silence is broken. Awakening to a galaxy that has forgotten their name, these immortal warriors march with grim purpose to reclaim a birthright stolen by time and erase all life that dares to occupy the stars.

Lore & Background

When the Necrontyr civilization crumbled under the weight of internal decay and the cruelty of the Old Ones, they sought salvation in the C'tan. The price was their very souls: a transmutation into soulless constructs of living metal, granting them immortality but stripping away the capacity for emotion or creation. Following this 'Great Sleep,' the galaxy evolved, giving rise to humanity, the Eldar, and other species who now occupy what the Necrons view as stolen property. As the Great Sleep ends, the tomb seals shatter not with a whimper, but with the grinding of ancient gears and the hum of reactivated power cores. Their return is no mere invasion; it is a cold, logical correction of history, driven by an unyielding mandate to strip the galaxy of all biological life and restore the Necrons' absolute dominion.

In Their Own Story

The silence within the tomb was absolute, heavier than six million years of cosmic dust. Then came the sound: the dry, rhythmic grinding of gears that had not turned since humanity's first ancestors crawled from the sea. High Lord Trazyn watched as the stasis field dissolved, revealing an Overlord rising from his sarcophagus—a monument of living metal and green light. There was no gasp for air, no thundering heartbeat; only the electric hum of recharging power cells and the sharp, final click of joints locking into place. The Overlord's ocular sensors ignited with a piercing emerald flare, scanning a galaxy that had changed beyond recognition. "The sleep is over," his voice echoed through the vast hall, synthesized and devoid of fear or hope. "Let the stars burn for our return." Outside, the first Gauss beams began to charge, painting the obsidian darkness in ghostly green hues as the dead rose to reclaim their empire.

Reader's Guide

While the Necrons operate on cold, unyielding logic, their leadership is often paralyzed by ancient dynastic grudges and rivalries dating back to the age of flesh. This fragmentation can be exploited by desperate foes like the Imperium or the Eldar, who may turn one dynasty against another. However, do not mistake this disunity for weakness; when united under a charismatic Overlord or the returned Silent King, Szarekh, they become an unstoppable force capable of decimating entire solar systems. They are the ultimate survivors, a tide of living metal that will never cease its advance until every biological life form in the galaxy is reduced to harmless dust and their empire rises again.
