Prompt

A magnificent cathedral carved entirely from luminous sapphire crystal rises within an immense subterranean cavern illuminated only by magical blue light. Towering crystal columns, soaring gothic arches, enormous stained-glass formations, shimmering bridges, cascading waterfalls, and glittering mineral terraces stretch endlessly into the distance, creating a breathtaking architectural wonder bathed entirely in deep cobalt, turquoise, cerulean, and azure hues. Tiny robed pilgrims slowly ascend monumental crystal staircases toward the cathedral entrance, emphasizing the overwhelming scale of the environment. Blue crystal flowers bloom along reflective pools while floating lanterns drift silently beneath the cavern ceiling, casting delicate reflections across polished crystal surfaces. The entire background glows with layered blue illumination, fading into atmospheric haze that creates extraordinary depth without losing the vivid sapphire palette. Painterly fantasy concept art, ultra-detailed stylization, intricate crystalline textures, elegant environmental storytelling, immersive masterpiece.
