You’ve opened the double doors, which are about 6 feet wide each. The 1 foot wide channel of filthy water, running from the pond where the elemental was, bisects the room, running about 40 feet directly into a 10’ diameter pool, which itself is next to a raised throne (the pond is partially between you and the throne). The room is dimly lit. The pond is ringed by kneeling figures – you can’t tell if they’re statues, people, moving, or fixed in place. Shadows dance along the walls and ceiling, which is about 25’ high, and arched. The room is about 10 feet wide on each side of the channel, with the right side of the room slightly wider than the left.
On the left side of the room, near the pond, are two openings that lead…somewhere. They are each only about 3’ wide, and are both dark.
The throne is on the right side of the room, with the pond directly in front of it. The cyclops has to turn about 45 degrees to its left to look directly at you, if it’s sitting in the throne facing the water. It’s like this: if the pond is a clock face, the throne is off the 5. The doors through which you came are directly off the 9; and the openings on the left-side wall are off the 11 and 1. You’re about 50 feet from the cyclops, which is looking directly at you and waving its hands around in a somewhat spastic ‘wax on; wax off’ motion. It’s also, for lack of a better term to describe the sound, chortling at you. Its single red eye glows in the dim room, providing the most powerful source of light, in addition to a few flaming brassieres along the walls.
