Central Cylinder:
The largest cylinder in the city is the Central Cylinder. The cylinder has a huge entrance, large enough for a number of tharlarion to enter side by side. This cylinder includes the bureaus and agencies that help run the city. The city Administrator also resides here and has his offices here as well. The High Council will have offices and meet in this cylinder. This meeting room may be referred to as the Chamber of the Council. In the Chamber, Council members will sit on stone benches, separated into five tiers. The wall behind each tier is painted a color to match the High Caste that sits on that tier. The highest Caste, the Initiates, has the bottommost tier. In the center of the room will be a throne for the city leader. No Council member or visitor is permitted to be armed within this room. Other city Councils are also likely to have offices and meet in the Central Cylinder as well. This Cylinder is likely to be located close to the middle of the city and often very large and important streets lead to it.
Caste Cylinders:
The books mention specific cylinders exist in some cities for the High Castes of Initiates, Physicians and Warriors. Little details are given on these cylinders though it does appear that they include dormitories for caste members, offices, training areas and more. It would seem logical that such cylinders also exist for the Scribe and Builders Castes, the remaining two High Castes. It is less certain if individual cylinders would exist for any of the Low Castes. If so, they would likely be for the more important Low Castes within a city such as the Merchant Caste.
Cylinder of Documents:
This cylinder is the place where legal and official documents are kept. This Cylinder is well protected against the threat of fire as such a disaster could devastate those city records.
Cylinder of Justice:
This cylinder is the location for the civil legal authorities within a city. The civil authorities share this cylinder with the Initiates who would use it for their own legal proceedings. Prisoners are kept here, especially those awaiting trials. Trials, before judges and/or juries, are to be held here. Court documents and legal scrolls are also maintained here. Executions, mutilations and other punishments under the city laws are enacted in this cylinder.
