Orikan, also known as Orikan the Diviner, is one of the most powerful of the Necron Crypteks, and is a potent chronomancer. Millions of Terran years ago, he was the astromancer of the Necrontyr empire's ruling Triarch, and one of the Silent King Szarekh's most trusted counsellors.
Orikan was the only one to then oppose the proposal of the C'tan Mephet'ran the Deceiver to grant the Necrontyr immortality through the process of biotransference, as he foresaw it would end in disaster, but his lone voice of dissent was ignored by the Triarch. Driven by loyalty to his race, Orikan submitted to the process and became one of the undying Necrons, forever undying and soulless in an android body of living metal.
