Setting:
By 2050, humanity has finally colonized Mars thanks to the efforts of one man, Jeff Murray. To avoid Mars’ high radiation levels and inhospitable temperature changes, he built a city underground. This city was named Mars MPO. Free of the constraints that often plagued businesses and researchers on Earth, scientists and entrepreneurs flocked to MPO.
