Vigesimi
For each of the eight Octarchs in the Inner Circle, there are twenty dignitaries known as Vigesimi who answer directly to them. Vigesimi are civil servants that deal with the law and civil order. They 160 Vigesimi are known collectively as the External Circle.
At the beginning of every year there is a meeting of all Octarchs and Vigesimi that lasts for several months. In this event they evaluate all expenses and revenue of the previous year, all complaining, problems, etc. Vigesimi normally come from the Craft Guilds of each level, and their position is hereditary. Nevertheless is not too rare to find some high citizens that are elected thanks to people acclamation, taking place of Vigesimi that are dead, that are judged inept or that are found to be guilty of thievery.
At the beginning of every season takes place the meeting of all Vigesimi of a level, generally (but not always) directed by the Octarch. During these short meetings the members of the External Circle can elect a new Octarch if the previous is dead or too old.
The Dome counts Datal Allavium, Davikel Iramok, Molveni Qued, Torkesyn Rabani, Brankyn Clamod, Otlidi Eam, Dazirah, Rikania Torwen, Adanius Ludrax, and Amidison Stronghand amongst their Vigesimi. And that is only half of them. Other levels admire how well the Dome is run.
