The Deceiver, known to the Necrons as Mephet'ran, is the C'tan of trickery, lies, manipulation and deception. It was because of the Deceiver that the Necrontyr died out, replaced by the mechanical Necrons. The Deceiver was shunned by its fellow C'tan long before the Necrontyr had even seen one. It was also the first C'tan to leave its stasis tomb, remaining active in the Imperium of Man many years before the awakening of the Nightbringer.
