Order of the Slayer

In the first age, in the first battle, when the shadows first lengthened, one stood. He chose the path of perpetual torment. In his ravenous hatred, he found no peace, and with boiling blood he scoured the Umbral Planes seeking vengeance against the dark lords who wronged him. Those who tasted the bite of his blade named him the Doom Slayer.

Few and far between are mentions of the Order of the Slayer are found. During the eruption of the Umbral gates, there was one who stood against the dark ones, he had many names. 'Doom Slayer', 'The Beast', 'The Destroyer', these were the common names found in ancient texts. After he suppressed the dark ones beneath his feet once more, he took it upon himself to teach others of the ways and the methods of those infernal and abyssal. These Blood Hunters where his mark, the mark of the Beast, proudly, as they walk amongst the Infernal and Abyssal Planes, keeping the denizens at bay. That is their eternal duty, their perpetual torment.
