Serenity

Serenity is the largest city on Luna and the first successful space colony. Located on the edge of Mare Serenitatis, it is comprised of three large domes and a solar array.

Serenity has 3 rail systems as well, two of which (A-B and A-C) connect the domes of Serenity, and Poseidon rail, which connects Serenity to its neighboring city of Poseidon.

History
Serenity was the site of the first successful dome habitat, which is now called Dome B. This dome originally held a number of hotels, most of which have been converted into apartment blocks at this time. As the tourism industry picked up steam, Dome A and Dome C were added, each with sealed rail system to connect to other domes in the compound.

During Luna's War, the city was turned into a virtual prison, with many citizens and guests held hostage inside the domes. After the Treaty of Tranquillitatis, the city was restructured to use fewer resources.

Political Climate
Thanks to the UN's Outer Space Treaty, no single country can claim ownership of any colony. However, a city this large does require a government, and as such the UN has appointed Elise Parker as the current administrator. Parker is generally disliked by the populace, as most of the citizens believe Serenity should be outside Earth's control.
