Space Opera Magic
Five planets orbit a mana-rich sun, developing their own cultures and ecology in isolation. Recently, they have achieved spaceflight to cross the perilous aether and begin exchanging culture.
(In ascending order of distance from the sun: Red, Green, White, Blue, Black)
White: The bold, beautiful space program of a distant, dying homeworld. Gleaming lunar bases, with a midcentury American/Soviet Futurism hybrid style. (Maybe it's literally a collaboration between the homeworld's two biggest nations?)
Blue: Giant, sharply-angled monolithic structures hovering unperturbed in a gas giant's atmosphere. The stones can “live” and “think” on an immense timescale, and obsessively archive the solar system's history for clues to their own existence.
Black: A shattered world that accretes scrap and debris from nearby, with rings of destroyed ships and satellites. A jagged, precarious space pirate aesthetic.
Red: A very “John Carter of Mars” aesthetic. Craggy canyons and mountains on a staggering scale, with an elaborate ascension-by-combat warrior hierarchy.
Green: The vintage sci-fi conception of Venus as a lush, overgrown land of dinosaur beasts. Jungle valleys are separated by miles of earthquake-prone wastelands. Each ecosystem has developed almost entirely in isolation.
