PROMPT:
A mystical observatory perched atop a craggy, mist-shrouded mountain, cloaked in an ethereal aura, with a mesmerizing, swirling vortex of vibrant blue, green, gold, and turquoise hues emanating from its core, surrounded by a tapestry of twinkling, diamond-like stars, set against a deep, velvety black sky, with soft, wispy clouds that resemble tendrils of silk, illuminated by an otherworldly, soft glow, with intricate, ancient stone carvings and mysterious, glowing runes adorning the observatory's walls, as if harnessing the secrets of the cosmos.
