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. Established by the Wyvern Circle in centuries past, the druidic group had abandoned the shrine in the 1100s DR and 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. It was called the Pool of Eldath by the Wyvern Circle. 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.

The three intact arches were two-way portals to other sites sacred to the followers of Eldath, but had very specific activation requirements. The portals only worked for good-aligned beings that carried a holy symbol of Eldath, and because each destination was an underwater location, the traveler had to assume the form of a fish just as they stepped through the arch. Experienced druids could use their wild shape ability, but other transformations were sufficient to open the portals.

The west-facing arch connected to the Duskwood Dell via the River Rimril in the Snakewood north and east of Eshpurta in Amn. The north-facing portal deposits a traveler in the lake surrounding the Elah'zad temple in the Scimitar Spires of Anauroch. The east-facing gate opened into a temple in the underwater Shalarin city of Us'daan in the Sea of Fallen Stars. The south-facing portal no longer functioned but its former destination was rumored to be near the shores of the Great Sea at the edge of southern Faerûn.

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. These spells likely came from a book sacred to the druids, known as the Tome of the Wyvernwater Circle, that was said to include spells such as flame shield, mold touch, touchsickle, and wailing wind. As of 1372 DR, the whereabouts of this book were unknown, but some of the menhirs were imbued with the essence of an ancient druid who could be queried via a stone tell spell. There were seven of these merged entities in the circle of twelve stones.

After the Bloodmoon Circle was established in the, the dirt around the Pool of Eldath was darkened by the blood spilled during their sacrifices. The pool also ran red after these ritual killings, but always turned clear when the dawn light touched the water. The entire area within the circle of standing stones was placed under an unhallow spell by the Malarites, giving it the effect of a magic circle against good, to which they added resist energy (fire) at each yearly renewal.

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.
