Grenhildr

Any theocracy eventually creates its own nemesis, and so it is for the Prismatic Circle. A former druid of The Prismatic Circle, Grenhildr was excommunicated for her belief that the Great Wyrm holds the key to the world’s salvation and thus should be revived. She believed that slaying elementals would eventually wake Gormadraug. To the shock and disgust of the Circle, she sacrificed several of the druids’ elemental guardians in an unholy ritual to the Great Wyrm.
Grenhildr was chased out of Thrull, but she was not deterred. Before long, she formed her own doomsday cult. The Cult of the Wyrm now stalks the land, killing mortals and elementals alike in a bid to revive Gormadraug. The reappearance of coldfire has only emboldened them, as they see it as a sign of their master’s imminent return.
The druid Grenhildr was once one of the brightest lights of the Prismatic Circle, and a protege of Grand Druid Hjadana. But a near-death experience on the winter tundra changed her, leading to a schism of faith that might tear Thrull apart.

The Salvation of Gormadraug.

Separated from the other members of a party returning from Borgund to Tyburn in the last days of light, Grenhildr was lost in a deadly blizzard and thought to be dead. But when she reappeared in Tyburn at the turning of spring, she brought with her a tale of having been saved and fed by prismatic drakes, and spending the winter in a sheltered cavern where Gormadraug the Great Prismatic Wyrm spoke to her. Grenhildr told of how Gormadraug’s long sleep was causing the wyrm’s power to fade to any who would listen, and how the north would come to apocalyptic ruin if that power ever ends. The healers of the Prismatic Circle marked Grenhildr as suffering from some unknown trauma after her season-long ordeal, but the young druid would not be quieted. In the Hollow Hill, she used unknown magic to slay a number of elementals in the circle’s service, claiming that Gormadraug would draw strength from feeding on their power. A death sentence was passed upon her in response, but more unknown magic allowed Grenhildr to escape Tyburn, and to carry her beliefs into the tundra and beyond.

The Cult of the Great Wyrm.

Everywhere Grenhildr travels, she preaches her belief that sacrifice in the name of Gormadraug will bring the Great Prismatic Wyrm back to the world and prevent the destruction of clan culture across the north. The most zealous supporters of the Prismatic Circle, including the warriors of Clan Völgr, treat her as a heretic. But many of the other folk of Thrull have proven surprisingly open to her views, having seen a century of the Prismatic Circle’s calls for blood and battle achieving little except the renewed resurgence of coldfire— which Grenhildr maintains is a sign of Gormadraug’s strength, and his antipathy toward those who refuse to aid in his awakening.
Members of what both Grenhildr and her foes call the Cult of the Great Wyrm operate in secret, exchanging hidden signs to identify each other, and gathering for fell rites in which elementals are trapped and sacrificed to feed Gormadraug. And though the cult’s numbers are still relatively thin, the disappearance of a number of mages of Clan Rune in areas where Grenhildr’s followers are known to operate have led to whispers that magic-channeling creatures of all kinds might be targeted for the cult’s fell rites.
