Mega-Colonies

The Mega-colonies of the Sol system were large cylindrical space-stations that could support upwards of billions of lives. While most were built in real space, some used Microplane Welding to save on space and construction cost.

Before the Inter-Colony war, there were 1,571 colonies with a total population of approximately 650 billion people. After the war, however, only 644 colonies remained, with a population of approximately 350 billion.
