The biggest city feature of the West Continent is that each city's top is adorned with a floating Aerial Fortress.
These Aerial Fortresses are larger than regular fortresses; for example, the Kingslander has been in service for 71 years and is technologically more outdated compared to these active fortresses.
In a sense, the West Continent hands over the soon-to-be-retired Aerial Fortresses to the Kingdom organization for repurposing.
They resemble a core Sky Island, like a black Iron Sky intimidating all citizens.
The Dukes mostly reside on the Sky Island; the Aerial Fortress is akin to the medieval Palace castle of Nobles in the Outer World, solemn and austere.
Floating airships in the city rise and fall, providing supplies for it.
Almost every hour, ten floating airships ascend and descend, and all officials wishing to visit a Duke must undergo thorough body searches and identity verification in order to board the airship and reach the fortress.
