PROMPT:
Create a photorealistic image of a mystical underworld realm, where iridescent fungi illuminate a labyrinthine network of ancient, gnarled tree roots that twist and turn like a maze of serpents, beneath a vaulted ceiling of gleaming, crystalline rock formations that refract and reflect a kaleidoscope of vibrant hues - emerald greens, sapphire blues, amber yellows, and ruby reds - casting an otherworldly glow on the mist-shrouded, gemstone-encrusted walls that appear to pulse with an inner, mystical energy, as tendrils of ethereal mist swirl around the base of a glowing, crystal monolith that pierces the heart of this mystical domain like a shard of radiant light.
