The Silent King, once named Szarekh, was the last supreme monarch of the Necrons and the ruler who bound their countless dynasties into a single vast empire in ages long past. It was he who struck the fateful bargain with the star-gods known as the C'tan, trading the flesh of his people for immortal metal bodies in the great biotransference that stripped the Necrontyr of their souls.
Horrified by the genocide his choice had wrought and by the tyranny of the C'tan, the Silent King ultimately led the rebellion that shattered those star-gods into fragments. Yet consumed by guilt at what he had done to his own species, he abdicated his throne and cast himself into exile beyond the galaxy's edge, ordering the Necrons into their long hibernation.
Now, in the galaxy's darkest hour, the Silent King has returned. Having witnessed the coming of the Tyranids in the intergalactic void, he seeks to reunite the fractured dynasties and forge the Necrons anew, ready to reclaim their ancient dominion over the stars.
