Luna

Thaddeus Sinclair’s deal brokered with the Martian’s  secured his clan’s escape to the lunar surface. Operating freight terminals on the surface of Earth servicing the enormous nuclear-pulse heavy lifters of the Martian Uplift Operation and trading for Martian technologies increases Clan Sinclair’s wealth and power on Earth and maintains a copious flow of supplies and resources, which Sinclair pours into the Lunar settlement. A generation later as the axis of powers brought into alignment by Thaddeus Sinclair solidifies (via the brutal pogrom of the Unification War) into a singular state (the Alliance) —a new deal brokered by Frederick Sinclair pours money into the Lunar economy. The program to construct and operate a vast network of Earth-Orbit defense platforms along with an associated system of Solar Power Stations (each the size of Manhattan Island) fuels additional expansion of the Lunar holdings. Emergence of the Alliance as a global power effectively ends the Martian Uplift program.
