The Tyrannid had been encountered by Humanity and the Eldar as far back as the 35th Millennium but this would have meant, there had been no significant encounters before the modern millennium between these two powers.Īctually yes, there was a three side battle (four, if you can humans) described in the "Devourer" novel published in 2014:Īnrakyr the Traveller, Necron overlord arrives at the awakening Tomb World.This plan worked with an amazing degree of success until the Necrons were awakened by the forces of the Imperium of Man in the late 41st Millennium to plague the galaxy once more. Meanwhile, aeons passed and the Necrons slept on, their machine slaves and constructs guarding them while they slept on Tomb Worlds that had been purged of all life to keep the Enslavers from their door. This was the Silent King's final order, and as the last Tomb World sealed its subterranean vaults, Szarekh destroyed the command protocols by which he had controlled his people for so long, for he had failed them utterly. The Silent King's final command to his people was that they must sleep for the equivalent of 60 million standard years but awake ready to rebuild all that they had lost, to restore the Necron dynasties to their former glory. Let the Eldar shape the galaxy for a time - they were but ephemeral, whilst the Necrons were undying and eternal. So it was that the Silent King ordered the remaining Necron cities to be transformed into great tomb complexes threaded with stasis-crypts. The Necron knew they could not continue to fight having spent so much of their resources against the C'tan. The last great threat to the Necron before going into stasis was the Eldar who were at the peak of their power.According to source materials, the Necrons were asleep after their last great wars and stayed asleep until the 41st Millennium when they were awakened by Humans.
