PROMPT:
Galactic Grotto: A mystical underwater cave hidden within a nebula, illuminated by bioluminescent flora and iridescent minerals. Vibrant turquoise, emerald, and amber hues dominate the scene, with subtle accents of deep blues and golds. A school of rainbow-tailed fish dart through the crystal-clear waters, surrounding an ancient, glowing artifact at the cave's center. Incorporate intricate, swirling patterns on the cave walls, evoking a sense of celestial wonder. Photorealistic textures and subtle light refractions should create an immersive atmosphere.
