PROMPT:
A mystical, ancient astronomical observatory hidden within a labyrinthine cave system, illuminated by an otherworldly luminescent glow emanating from intricate, swirling patterns etched into the walls, as if the celestial bodies themselves have inscribed their secrets onto the stone, surrounded by a halo of iridescent mist that shimmers with an electrifying turquoise hue, while glints of polished bronze and copper accents reflect the soft, ethereal light, set against a deep, rich indigo background that seems to pulse with the rhythm of the cosmos, evoking an aura of ancient wisdom and mystery, with an overall sense of vibrant, electric blues and golds dominating the palette, as if the very fabric of reality has been woven with threads of stardust and magic.
