The Golden Orb allows for agriculture to flourish in direct proximity to Order, though raids conducted by Iron Choir members on nearby caravans suggest Seabed City is not entirely self-sufficient. Otherwise, the city and surrounding areas are desert-like in climate.
In accordance with the Iron Choir's doctrine, Seabed City's infrastructure is entirely analog, and its citizens rely on simple machines to conduct everyday operations and defend their city. Seabed City is also in a networking dead zone, meaning that those in proximity to it cannot connect to The Mesh; short-range communications and broadcasts will work, however.
The events of Episode 17 took place primarily in Seabed City.
