Archonus (Arr-Kann-Nuss)

Archonus lies high in the sky above Hexcross Bay but below the Aetherward. It exists as an enclosed environment that automatically generates the weather, climate, and overall environment.

Archonus is the floating center of Runevale and holds many Noble Houses, the House of Commons, and the manors and residentials of the affluent, rich, aristocratic, and those who wield influence and power.
It holds great import to the city, and is guarded by a legion of automaton constructs called the Arcwardens. It is a rare occasion for commoners or those of lower wealth to find themselves on Archonus and suspicion can be aroused if those individuals are sighted.
But if one can find the coin and influence, there is plenty to gain
