Warhammer 40,000 Codex

In the darkness of the ancient past, the Necrons ruled the galaxy. Such was their mastery of technology and drive to conquer that not even the Old Ones of legend could stand against them. Yet such unremitting war left the galaxy ravaged. Knowing that the recovery would take millions of years, the Necrons took to their stasis-crypts, there to sleep away the aeons until the galaxy was fit to reclaim. In the long millennia since, the younger races of the galaxy have gone about their petty affairs, little realising the peril slumbering beneath their feet. Now the hour of awakening has come at last. Let the galaxy beware - the Necrons are rising. 'Their number is legion, their name is death.' - Eldrad Ulthran
