[The Wicked and the Warped] Was the War in Heaven 10 million years?
I notice most dates for when the Necron great sleep happened is 60 million years ago (including in the novel). Yet in the book Orikan states it has been 70 million years since he wore clothes, implying this was when biotransferrence took place. So this would imply that the time between biotransferrence and the acceleration of the war against the Old Ones and the great sleep (after the defeat of the Old Ones) was 10 million years.
I don't think GW understands how long a period of time that is.
