The Treaty of Heinlein (named for the Lunar colony complex) helped end open fighting in the Worlds War. Alongside it came Melange Mining's consolidated helium-3 monopoly and new institutions: Universal Nations, Space Elevator Authority, and Martian Colonial Authority.

Martian critics argue the Martian signatories were Earth-born and corporate-aligned; native clans claim they never agreed to peace. That grievance fuels the ongoing Martian Colonial conflict.

Story hooks: treaty loopholes, "war criminal" corps still in power, Loonie independence cells, Melange monopoly enforcement.
