Location from Red Rising by Pierce Brown
Earth's moon and capital of the Society. Seat of the Sovereign, playground of the most powerful Gold families, and the political center of the solar system.
Luna is where power lives. Every Gold family of consequence keeps a residence here, every Copper bureaucrat of ambition angles for a Luna posting, and every Pixie and Pink knows that Luna sets the fashion the rest of the worlds follow. The Sovereign rules from the Citadel with a network of Praetorians, Politicos, and fear that reaches every corner of the system. The moon itself is a monument to Gold excess — gravity gardens, zero-g ballrooms, gladiatorial arenas where Obsidians fight for entertainment. Beneath the glitter, Luna runs on the same exploitation as everywhere else: Reds, Oranges, and Browns doing the work that keeps the lights on while Golds take the credit. When the Rising comes to Luna, it comes for the throat. Taking Luna means taking the Sovereign, and taking the Sovereign means breaking the Society's spine.
A domed megalopolis of spires, glass towers, and palatial estates built into and across the lunar surface. Gravity generators maintain Earth-standard conditions inside. The Citadel dominates the skyline — the Sovereign's fortress-palace visible from every district. Outside the domes, the grey lunar wastes stretch to the horizon.
