PROMPT:
Galactic Grotto: A luminous, iridescent cave hidden within a glowing nebula, teeming with bioluminescent flora and fauna that shimmer in shades of electric blue, emerald green, and radiant gold, as tendrils of glittering stardust swirl around ancient, crystalline structures that seem to pulse with an otherworldly energy, all bathed in a soft, ethereal glow that captures the essence of a mystical, interstellar sanctuary.
