- "Dwindling energy and rare-earth resources on Earth lead to Mars colonization and terraforming. 30 years ago, the Settlement Defense Front, a brutal insurgent group, led a coup that resulted in the extermination of all Earth-loyalists on Mars. They formed their own military junta - and instituted martial law planet-wide. After the loss of Mars, the countries of Earth formed the UNSA to help facilitate diplomacy in space-trade. Since the Secession War, resource trade continues, fueled by Earth's need for energy, and Mars' need for weapons and technology. After years of military buildup by the SDF and repeated reports of human rights violations on Mars, certain countries instituted trade sanctions against Mars. The SDF saw this as an attack of their sovereignty and led directly to their invasion of Geneva."
