You cautiously descend the stairs, with Gustav leading the way. From the main tunnel, wide steps lead 100 feet (30 m) down into a massive chamber. The hall is approximately 400 × 500 feet (120 × 150 m), with ceilings soaring more than 100 feet (30 m) high. The hall is so vast that only loud noises echo—ordinary voices are damped by the huge space.
Numerous torches light the way and illumine the vast courts within, reflecting everywhere from the gleaming black marble walls. The floor is of black marble flecked with white. The floor is exceptionally shiny and slick. Numerous ebon pillars support the enormous vaulted ceiling. You shine your torch along the length of the closest pillar, and the top seems to splay out into the tops of a black tree, the branches of which visibly sway to and fro in extra-dimensional winds.
Ahead are stairs
(2) leading to a floor (or somewhere...) lower than the hall. They disappear down into a hideous, glowing ruby mist that pours up from below. Occasional ghastly shrieks and moans can be heard drifting up into the main chamber.
A large square pit
(3) in the middle of the cavern turns out to be a pool of water, 75 feet (23 m) across and filled to within 8 feet (2.5 m) of the top of its stone wall. This water looks totally black and featureless. A set of narrow and slippery black marble steps without railings leads down into the pool. Tethered beside the steps is a jet-black ceremonial raft.
An altar
(4) constructed from white marble stands beyond the pit, about 25 feet (7.5 m) square at the top. From three sides, steps lead 15 feet (4.5 m) up to where a sarcophagus rests. Stone braziers, which burn with a sickly yellow light, are built into the four corners of the altar.
Beyond the altar is another structure: a hideous double throne
(5) of vile green, sweating stone, carved with numerous images of violent and cruel acts performed by humans and other horrifying, almost mythical-looking, creatures. The throne’s two seats are designed for human-sized figures. The throne block stands 30 feet (9 m) above the floor. To the front only, facing the hall, a set of narrow and precarious steps leads steeply down to the floor of the hall.
As one faces the hall from the throne, a long bridge leads sideways to the left wall of the hall. Its supports are also carved with disgusting figures and writhing tentacles. The bridge is of the same bilious green, weeping stone as the throne block, and has no railings. Its surface is 30 feet (9 m) above the floor.
A few feet out from the where the bridge joins the chamber wall stands a stele
(6). It is very similar to the one you saw at Misr House in England.
In the rear wall of the Great Hall, behind the throne, is an enormous irregular hole
(7), about 100 feet (30 m) wide. The hole is pitch black.
