The Necrons are a deathless race of alien androids, rulers of the galaxy in a long-forgotten era. Now, having slumbered in stasis for millennia, they are rising up to conquer it again. Clad in self-repairing bodies of living metal and wielding weapons that harness the most devastating energies of the cosmos, the Necrons are a terrifying enemy. Fearless, relentless, and utterly without mercy, they advance in serried ranks and lay down withering storms of fire fit to annihilate even the mightiest of foes. The hyper-resilient Necron soldiery are supported by murderous specialist units, techno-sorcerous war machines, mindless Canoptek constructs, and shards of shattered star gods. They are led to war by undying nobles wielding weapons of devastating power, driven by the absolute conviction that they are the rightful rulers of the stars. And if the long sleep has reduced many Necrons to mindless monsters, or ravaged their sanity and transformed them into murderous demigods? Such madness only makes them an even greater and more terrible threat.
