Crystalline oceans and refracted starlight
A warm sea lit from below. The crooner sings from a stage that is also a boat. Bioluminescent tide rolls in on the beat. Smells of salt and applause.
Sprawling vertical cities illuminated by neon. Data is the most valuable currency. Violet-lit caverns house ancient crystalline beings.
Subzero plateaus, bioluminescent spires, and thin breathable layers near the surface. Sensors glitch near resonance storms.
