The Twin Domed Cities of Sodom II and Gomorrah II are currently holding out against a planetary siege from above...in the form of 2 massive anti-planetary dreadnoughts from the Colonial Authority. Such is the price of attempting to break away from the dominion of the Inner System Coalition.
About this creation
In response to the assault, the twin cities launch 2 of their largest battle cruisers, the Argo and Ajax. However, these 2 mighty vessels are but a fraction of the size and power of their opponents....
Here we see the massive bridging facility between the 2 cities. This structure houses life support systems and serve as a transit/customs facility between the 2 habitats. It is also home to the space elevator that links these 2 planet-bound habitats to the Orbital City of Babel.
Painted in blue is the hangar for the common space port facility. It is large enough to accommodate the passage of vessels as large as cruisers, with underground hangars large enough to berth several capital ships.
