Terra Expanse

In the 24th century, humanity has colonized the inner solar system. Earth is overpopulated and ruined, Mars dominates the Inner Planets, while the Belters of the Asteroid Belt and outer moons live under scarcity and exploitation. A fragile ceasefire between the factions is constantly threatened by piracy and sabotage. Mysterious alien structures and anomalies called the Silence have begun appearing at the system’s edge. Whoever controls them could destroy the balance of power… or save humanity.

This world is heavily inspired by The Expanse, particularly its grounded vision of humanity’s expansion into the solar system, the political tensions between Earth, Mars, and the Belt, and the dangers of an unknown alien presence. It is not an official adaptation, but an original setting that builds on similar themes while introducing its own factions, locations, characters, and mysteries.
