Features
The city is built out of a mix of the purest marble mined from parts of the Moon, as well as lesser minerals. The entire city structure, like many planetary cities, is built around it's main governance building, in this case the Moon Castle. The city itself is divided into three walled sections or phases as they are sometimes referred to in texts.
Central Phase
Carved directly from the remains of an ancient mountain, this section is where the Moon Castle lays, protected by a thick stone wall and guarded by three observation towers, two on the right side and one on the left size. Within these walls lay the estates and homes of the highest ranked nobles that live on the moon, nestled close to the edge of the Castle itself. These include the Planet Houses, what would normally be called embassies in the present day. The pathway and entrences to this section of the city are a need to know basis and require proper clearance to do so.
