Ring Caverns (Oryndoll)

The Ring Caverns together were the main district of Oryndoll. They are connected to the Thrall Caverns district. The district housed many of the illithids, ceremorphs and golems that lived in the city.

Description
The walls of these caverns were heavily engraved to give the appearance of exposed brain tissue. The outer walls of the district have religious doctrine mixed with directions in Qualith written on top of the engravings. The caverns also were humid.

The general architectural layout of each cavern was a series of tubes.

At the core of each ring cavern was a sphere where most social activity between illithids occurred in shallow basins. The walls of the spheres were peppered with the private living quarters of many of the illithid denizens of the city on all levels, much of which was only accessible via levitation or other forms of flight magical or mundane.

Connected to the core of each ring cavern through tubes was an external tube in the shape of a ring that circled around it. This external tube also connected to the external tubes of other ring caverns as well as had several carved alcoves used by Creeds and ulitharid leadership.
