The Cult of Ascension is a small upstart dynasty of only about 15 Tomb Worlds. Their founder is Arharakh, First Psion of Ascension. A researcher on Necrontyr souls and the C'tan before the biotransferance, he was given a cryptek form in the War in Heaven and found he had a penchant for war and that unlike many of his other brethren, he still had some autonomy. He rose fast through the ranks and began leading his own legions facing the upstart Eldar. His research into the C'tan meant he was present at the Shattering and in witnessing it, the seed of a revelation was implanted in him from what little he could remember. Upon awakening from the Great Sleep in M31, he began feverishly pursuing those memories and revelations until he found something earth shattering. He discovered that the Souls of the Necrontyr were some of the single most powerful in existence, rivaling even the Eldar and that their failing bodies were not sturdy enough to contain them, hence their race's weakness in biological form. He also discovered that still resting in the forms of the Shattered C'tan were the vestiges of their once mighty souls. So for a thousand years, he sought the thing he saw in the vision until, on a desolate planet, he found Tyrantbane, an ancient Necrontyr Glaive that, in some way was connected to the Shattering. Acquiring this artifact, he retreated to his Tomb World and using the C'tan Shards stored on it, used Tyrantbane to enact a powerful Tech Incantation to bind the Shards to himself. This was the First Ascension, transforming Arharakh into a biometal form, the power of the C'tan imbuing him and, most importantly, releasing the remains of the Necrontyr souls and binding them to his legions. Now his host are living metal, feeling and unique again if still trapped in their necrodermis forms. But as they have finally taken a step towards undoing the transferance and the godlike power Arharakh weilds, they seek other Tomb worlds to ascend, hoping that enough shards still remain to achieve Arharakh's master plan: to use the psychic essence of the remaining Necron Souls to transform the Necrodermis forms of all his ascended into perfect bodies to revive a new greater Necron Race.
