Antigos esqueletos de cobras entrelaçados em uma caverna luminosa

Two ancient king cobra skeletons, each the size of a bus, intertwined and coiled around one another, rising upright and looming downward with dominance. Their massive skulls flare with jagged fangs, cracked bone etched with arcane runes and ancient battle scars. The scene is set deep inside a vast underground cavern, illuminated by eerie bioluminescent fungi, glowing crystals, and drifting green necromantic mist. Shafts of dim torchlight and magical embers cut through the darkness, casting dramatic shadows across the rib cages and cavern walls. The atmosphere is high fantasy, dark and epic, reminiscent of Dungeons & Dragons, with a sense of forbidden magic, forgotten gods, and legendary danger. Ultra-detailed, cinematic composition, dramatic lighting, epic scale, realistic bone texture, dark fantasy concept art, 4k quality, painterly realism.
