Oboron

Oborom is a great city on Axial's northern hemisphere. It is built over the Yurionic Sea and thus is built on struts.

Structure
The city is supported by struts. The city is comprised of a series of towers which act as all the buildings. These are built around a central building which houses the Grand Oboron Station for the star ferries which go between Ignis and Glacies depending on their rotational positions. Out from the hub, the buildings form four rings with each class of people. The roads and sidewalks are catwalks.

Ring 1. Upper Class
The housing and life center of Oboron. A place of true riches for those with enough Kila to live there.

Ring 2. Middle Class
Housing to families. The schools and public medical buildings are located here.

Ring 3. Lower Class
The lowest class lives here. These people don't have enough money to live in the inner rings.

Ring 4. Abandoned City
The name says it all. No one knows why it's abandoned. It is currently under investigation by the Librarians.

The Underground
A network of pipes which run under the city which was originally built for easy access for workers to repair the struts. It's almost another city unto itself.
