However, he has earned his dire moniker by the countless bloody deeds he has perpetrated across a hundred battlefields and more.
To be named as a target of the Headsman's ire is a truly horrifying prospect, for to date, none who have been so named have escaped their fate.
The Headsman is only ever known to have one target at a time, never announcing another until his boast is fulfilled and his victim's skull laid before the Brass Throne of Khorne.
First witnessed by Imperial forces on the world of Khazant, the Headsman has been encountered leading a warband of his fellow Khornate Berserkers as well as on his own. Of all the bloodthirsty murderers fuelled by the bloody essence of Khorne, the Headsman is feared as the most savage and unrelenting.
He wields a mighty two-handed chainaxe with which he beheads his foes, often a dozen with a single sweep. His features are obscured by an executioner's hood, little more than his baleful eyes visible.
However, it is not just his appearance that has earned the Headsman his title, and it has been noted in Watch Fortress Erioch's Chamber of Vigilance that his deeds are neither mindless nor random. Rather, the Headsman announces to his followers and to all who will listen who his next target will be, and then sets out to slay them at any cost.
Such targets are often the leaders or champions of the Imperium's armies of the Achilus Crusade, though on occasion they have been spiritual leaders or even high administrators. None can discern any reason in the Headsman's choice of target, but once the name is announced the victim's doom is all but sealed.
To date, the Headsman has announced the name of, and subsequently slain, three Space Marine Company Champions, a Chaplain, seven Astra Militarum Colonels, two Adeptus Titanicus Princeps, a Cardinal-Aquilus, and a Commissar-General.
The Chamber of Vigilance has received intelligence that the Headsman has recently embarked upon a new hunt, but as yet the identity of the target is unknown.
