The Sol System

Humanity has reached the stars. Earth is overburdened. Humanity is scattered across the solar system, on Mars, on Jupiter's Moons, and out in the Asteroid Belt. Fifty years ago, Earth and Mars split, each seizing control of a portion of the Asteroid Belt and splitting the Jovian moons between them, at least until the residents of Jupiter's moons rose up and declared their sovereignty. Now, the Belt is further split, between Earth, Mars and the Jovian Union, and Belters have no autonomy and no freedom.
