Wyvernstones of Hullack

The Wyvernstones of Hullack were a group of menhirs at a site sacred to Eldath located in the Hullack Forest of northeastern Cormyr. By the, the site had been taken over by the Bloodmoon Circle, a sect of Malar-worshiping lycanthropes that were part of the People of the Black Blood. Few, if any, beings alive at that time knew that the Wyvernstones were much larger than what was visible above ground and that they held up the roof of an ancient subterranean grotto used as a burial vault by the elves of House Amaratharr.

Location
The Wyvernstones were hidden among the trees in the southwest quadrant of the forest, north of the eastern branch of the Wyvernwater.

Structure
Above ground, each menhir was approximately tall and  in diameter. The twelve of them were arranged in a circle about in diameter. The north-, east-, and west-facing pairs of stones were capped by a table stone forming an arch. The table stone above the southern arch laid cracked and broken at the base of its menhirs.

A small pool of clear water about in diameter adorned the center of the circle of standing stones. No plant or animal life obscured the stone lining of the pool. It was filled from below by a tiny spring and reached deep at its lowest point. The area between the pool and the menhirs was overhung by the surrounding trees and consisted of hard-packed dirt.

Atmosphere
The outer surfaces of the twelve standing stones were adorned with carvings of wyverns and were free of lichen or moss. However, the sides facing the central pool were nearly covered by a thick layer of these plants. Beneath the obscuring plant life were ancient magical runes, some of which still contained Eldathyn spells that could be cast if one knew how.

lies in the center of the circle and despite the bloody sacrifices and rituals tainting its waters nightly, upon the morning it becomes pure again with the first rays of dawn.

Hidden under thick moss on the inward facing surface of each stone are druidic runes. If cleared and deciphered they form several spells often employed by druids of Eldath. The outer surface of each stone is entirely devoid of moss or lichen, leaving several intricate carvings of ancient wyverns visible to anyone who should discover the fabled Wyvernstones of Hullack.

Interior
They once marked the burial glen for the elves of House Amaratharr until their eventual retreat and were later used by druids of the Wyvernwater Circle. In 1363 DR Lycanthropes linked with the People of the Black Blood discovered the stones and formed the Bloodmoon Circle, and use the site to conduct their bloody rituals.
