Also known as aquastats or hydrostations, the submersible cities of the Eurasian Alliance
The Rock of Gibraltar, once a stalwart of British power, the gate to the Mediterranean, now is a fortress for the Eurasian Alliance. It's fair teeming with neo-Soviets and submarines.
Except, it doesn't have to be. Nighttime can be a relaxing, peaceful time in the world, when nature rests and soft shadows cover the ground. Not every night has to be filled with vampires, ghosts, beasts, and things jumping out from dark places.
