The Expanse - Sol System

The Sol System—humanity’s cradle. The discovery of the protomolecule has changed everything, and tensions between Earth, Mars, and the Belt are white hot. The pressure rises as the exodus through the Ring gate escalates, and war seems inevitable. Opportunities abound for shrewd crews willing to take risks.

Sol System provides information on the governments, corporations, and organizations that vie for power within the star system that birthed humanity. Details on trade between the planets and stations of the solar system and beyond lie within, along with an in-depth overview of the layout, operations, and people of two of the most important locations in the Belt, Tycho and Ceres stations. Sol System also offers a comprehensive guide to running planetside stories, either as a prequel or a campaign, as well as rules for creating and running corporations, media outlets, security firms, or religious groups that jockey for money and influence between Earth, Mars, and the Belt.
