The multi-Color free state Darrow and Mustang built from the ashes of the Gold Society.
The Solar Republic is the fledgling government forged by the Rising after the fall of Octavia's Society, ruling Luna, Earth, Mars, and now Mercury as free worlds. Its sigil is the fourteen-pointed star, and its power is split between a Sovereign—Mustang, who deliberately weakened her own office in the New Compact—and a 140-seat Senate of ten senators per Color. Its Free Legions, led by Darrow, have fought a decade of war to push the Ash Lord back to Venus.
But the young state is fracturing: two hundred million dead, famine and Obsidian piracy, lowColors packed fifteen to a room while highColor aristocrats keep their towers, and a rising Vox Populi accusing its own war-hero of becoming the tyrant they overthrew.
The central polity of the story; the imperfect free republic whose survival and soul are the stakes of the war.
