Ancient Remembrancer's sketch depicting Exodus, the infamous Alpha Legion assassin

Exodus was an infamous assassin of the Alpha Legion that operated during the Great Crusade and Horus Heresy eras during the 30th and early 31st Millennia.


None can say whether Exodus is a single individual or one of several supremely skilled assassins operating at the behest of the uppermost echelons of the Alpha Legion. Certainly the name, or coded identifier "Exodus," had appeared in multiple vox-chains and order logs in many different war zones, sometimes contemporaneously. This in itself was unlikely to be accidental given the Alpha Legion's mastery of deception in all its forms.

Whatever the truth, the Legionary known as Exodus ranked amongst the most skilled killers outside of the Assassin Clades of the Officio Assassinorum during the Great Crusade. His skill-at-arms was born of the convergence of the will, physiology and conditioning of a Space Marine with the fieldcraft and panoply of arms and wargear of an assassin. So adept was Exodus that he was said to rival even the marksmen of Clade Vindicare in his ability to insinuate himself into position and deliver the killing shot at the pivotal moment in a campaign. Some histories claim that as many as a dozen worlds were brought into Imperial Compliance with only a single shot having been fired by Exodus, who could achieve with one round what the expenditure of billions of rounds, charges and shells might never bring about. His ultimate fate is unknown.
