From Warhammer 40k - Lexicanum
|Sometime after the birth of the Universe||First appearance of "life" in The Galaxy. Parasitical Star vampires, the first self-aware entities, appear.

The Necrontyr are eventually out-manoeuvred by the Old Ones and exiled to the edges of the galaxy and into their own homeworld.||Codex: Necrons (3rd Edition) pg. 24: "The Necrontyr" and "War in Heaven"|
|Unknown||Twisted by a hatred towards all life and looking for weapons to use against the Old Ones, the Necrontyr create a body for the star vampire feeding upon their own sun, creating the Night Bringer. They create more bodies for other star vampires, turning several star vampires into the C'tan, called Yngir by the Eldar. The ever-hungry C'tan discover their ultimate delicacy: Souls. The C'tan known as the Deceiver tricks the Necrontyr with the promise of immortality and the C'tan turn all living Necrontyr into Necrons, feasting upon their souls.||Codex: Necrons (3rd Edition), pg. 24: "War in Heaven";|

|Unknown||The God War begins. The Old Ones are forced to retreat into besieged bastions. The C'tan and their servants, the Necrons, dominate the Galaxy. The "young races" are treated like cattle by their new terrifying masters, the C'tan. Life begins to grow more and more scarce in the galaxy. The C'tan, manipulated by the Deceiver, begin to slaughter and to consume each other. The desperate Old Ones influence many warlike young races like the Eldar, fostering their ability of using the energies of the Warp, the Achilles' heel of the C'tan.||Codex: Necrons (3rd Edition), pg. 25: "Necron Ascendancy"|

|60 million years BC (approx)||The Pandora's box of Warp-magic opens. Several predatory Warp-entities appear, hunting and consuming psykers. Trying to defend their last remaining strongholds from destruction the Old Ones create the Krork (Orks) and the Jokaero, but it is simply too little, too late. First among the Warp-denizens, the Enslavers appear in a locust-like fashion.||Codex: Necrons (3rd Edition), pg. 26 "Apocalypse Looms"|
|60 million years BC (approx)||Szarekh, the Silent King of the Necrons, succeeds in leading his people in a revolt against the C'tan. The devastating conflict sees the C'tan enslaved. However weakened from their wars against both the Old Ones and C'tan and faced with a myriad of new threats such as the newly born Eldar, the Silent King decides to have the Necrons go into dormancy on Tomb Worlds. He puts himself into self-imposed exile into the void between galaxies.||Codex: Necrons (5th Edition)|
|Unknown||Many minor creations of the Old Ones survive and slowly evolve on their own, including "comical tree-beasts" who will slowly evolve into Humanity. Perhaps because of compassion, or simply reluctant to extinguish another life-form, the Eldar decline to wipe out these mon-keigh. Unknown to almost anyone, Humanity's future generations will produce Untouchables (at a rate of less than one in a billion) because of ancient DNA manipulations of the "Devoured Ones". All surviving and future races are imprinted with a fear of death because of the slaughters and powers of the Night Bringer, with the sole exception of the Orks.||Codex: Necrons (3rd Edition), pg. 28: "An Age of Slaughter"|
