So I'm writing the lore for a Necron Dynasty, called the Anutekh. They specialize in nanotechnology, with which they're working on a solution to the Necrontyr's ages-long physical ailments and misfortunes. Obviously, Necrons and everything affiliated with Warhammer 40k belong to Games Workshop.

Below is a massive lore dump so be warned. TL;DR I'm doing something I'm disappointed I'm not seeing more of, adapting the famously anthro-esque Egyptian deities into Necron armies, like Age of Mythologies or something.

The Anutekh design and build a series of nanobots which produce synthetic plastic similar to how a spider spins silk. Only this material is used to build pseudo-flesh and organs, which are supported by a bloodstream of a single, curiously viscous purple fluid.

The first bodies, or vessels are they are called, were raised on a sort of Eden world, with the intent of building a population of bodies for the Dynasty's elite and their trusted servants first. But the first individuals to undergo this were Shepherds of sorts, guardians of the otherwise near mindless vessels. A good way to think of them on their own, is like the Eloi from Welles' The Time Machine.

The intent being, for the Anutekh themselves to perform a mass transference into their also soulless bodies, that,

1. Lack the lingering curse of radiation poisoning that plagued the entire Necrontyr race.
2. Allow them to regain some semblance of the culture they once had prior to the War in Heaven.

At any rate, this quiet world naturally comes to interest the Imperium which at first they believe to be a feral world occupied by simple, neolithic xenos, until their Apothecaries start dissecting the first vessels they capture and come to realize their artificial nature. Naturally, all this absolutely pisses off the Anutekh, and the entire operation is forced to change.

Then, as is typical in 40k, a lot of death and destruction ensues. More later!
