Gyyagin

Gyyagin is a fictional monster created by Stephen King for his short story "Jerusalem's Lot". A giant extraterrestrial worm that transforms its human followers into undead servitors, Gyyagin is itself identified as a servant of "Yogsoggoth" (possibly Yog-Sothoth), and is heavily implied to be the titular worm that the grimoire known as De Vermis Mysteriis (English: Mysteries of the Worm) alludes to.
==Description==
Gyyagin is a massive worm that burrows under the ground in the area around the town of Jerusalem's Lot, Maine. Descriptors and sobriquets include "the Worm from beyond space", "Star-Eater" and "Blinder of Time". Its body is segmented, at least 5 ft wide, grey in colour, and produces black slime as it moves around its tunnels. Wherever it crawls over, the ground's vegetation withers and turns white. Its mere proximity seems to have a noxious effect on the local inhabitants, precipitating the birth of eyeless or noseless children.
Like many Mythos deities, Gyyagin demands bloody sacrifices. Its victims are apparently killed by constriction, as the gargantuan worm squeezes them until their blood vessels are ruptured.
Gyyagin is perhaps most notable for transforming its human followers into undead creatures (referred to at one point as nosferatu) which live in its tunnels with it. Blood relatives of these cultists seem to be subtly attracted to the area that the Worm inhabits, but it's not known whether this psychic link is formed by Gyyagin or by the undead relatives themselves.
Additionally, Gyyagin is known to have some kind of connection to the grimoire known as De Vermis Mysteriis, to the point that burning the book will force the deity to retreat and abandon pursuit of its target, at least for the time being. (: "Jerusalem's Lot")
==Behind the Mythos==
The town of Jerusalem's Lot first appeared in Stephen King's 1975 novel 'Salem's Lot. In the novel, the vampire Kurt Barlow establishes himself in the town by making a pact with a powerful undisclosed entity, offering a child named Ralphie Glick as a sacrifice to it. Given Gyyagin's domain over the same town, penchant for demanding sacrifices, and association with undead / nosferatu, it wouldn't be much of a stretch to assume that the being that Barlow made a pact with might have been Gyyagin.
