Lunea Prime, capital city of Népthelion, one of the few regions in Neptune's “habitable zone”
Lunea Prime, the home of Aoi, resembles a large Earth-based capital city, but with an ultra-futuristic twist. It features streets, residential neighborhoods, futuristic Haussmann-style buildings, and skyscrapers, all illuminated by highly advanced magical technology (floating holographic panels, magically projected advertisements, flying vehicles, etc.).
