Prophet of Truth (Earth-8756)

The Prophet of Truth, born Ord Casto, was the leader of the san'shyuum Hierarch triumverate and the Covenant High Council during the 9th Age of Reclamation and the First Contact War. Cunning, ruthless, and a masterful manipulator, Truth started his life as the Minister of Fortitude, and later orchestrated the genocidal war against humanity following a shocking discovery, which he kept a secret, about the true nature of the forerunners and the Path, which saw the death of billions until his death in December 2552.
