Seafloor Cities

Enclosed megastructures resting on the abyssal plains, these undersea cities withstand crushing pressure and eternal darkness with reinforced hulls and advanced life-support systems. The isolation of these colonies makes them difficult to reach, providing security from external threats but hampering trade.
