The Worm that Devours
After spending an eternity feasting on the core of dead stars, the Worm that Devours have found the taste of human misery to be an addiction it can never shake. It feasts on terror and on the essence of those who decay while still alive, both available in abundance on the killing fields of the Long War.
The Worm that Devours have learned well the value of restraint and is one of the Covenant. To quell the depth of its hunger, the Worm has subdivided itself many times into various forms that prowl the battlefields of the long war for the feast it desires. Most of these forms combine elements of fire and crawling, creeping things with too many legs and too many claws.
The Grinning Man Unknown to the rest of the Covenant, the Worm that Devours has managed something that no other Occultarum have - it has pierced the shroud and manifested in the world of mankind. The very weakest of its subdivision managed to slip through in the shape of the Grinning Man. This sub-self of the Worm has the shape of a crude simulacrum of a man, with pale puffy skin and a face devoid of features save for an impossibly wide, toothy grin. It wears whatever outfit its observer might, though in the quality of a poor imitation. The Grinning Man is weak and only able to manifest in the parts of the world where the influence of the Occultarum is felt most keenly, areas of high strangeness. So far, it has done nothing and only watches - though a particularly concentrated artillery barrage once dismantled its corporeal form and forced the Worm to reforge it.
