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, known as the Elfhold, 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 granite 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.

The Pool of Eldath itself was a bi-directional portal to the Elfhold directly below it. The portal could only be activated by people with elven blood that stepped into the Pool with a white dove in one hand and the symbol of House Amaratharr carved on a stone in the other. When triggered, the portal opened for a few seconds and allowed other beings to pass through. The travelers arrived in the other half of the Pool of Eldath—a pool the same size and general shape, located between the bases of the same twelve menhirs that encircled the waters above.

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 fire resistance at each yearly renewal.

Interior
The menhirs were in diameter at their true base and tapered gently as they rose up through the ceiling of the grotto some  above the floor. Elfhold was illuminated by a single diamond that hovered about above the Pool and shown with a soft brilliance that bathed the area in starlight. The gemstone was a tel'kiira attuned to the Amaratharr family.

The entire Elfhold was roughly a compressed sphere over in horizontal diameter with burial crypts cut into the walls all around. Each crypt was sealed with a capstone engraved with life-sized scenes of elven life that dated back before the founding of Cormyr. The twelve columns were inscribed in Seldruin, using Hamarfae script, with a litany of the accomplishments of those interred. All the crypts contained the remains of members of House Amaratharr except for one. The elf-friend Hullack, namesake of the surrounding forest, was a human druid that, according to the scene on his capstone and the writings on the nearby pillar, stood with elven forces against beholders, goblinoids, and evil fey.
