A majestic marble demon, fearsome and powerful, with a body entirely made of smooth, polished marble. The demon's surface features natural veining typical of marble, with a white base color and intricate gray, blue, and gold patterns running throughout its form. Its horns curl menacingly from its head, and its muscular body is poised as if ready to unleash its fury. The demon's eyes are deep, hollow sockets that exude a sense of ancient malevolence and dark power. The demon is standing on a rugged, rocky mountain peak, the cold wind causing small flakes of snow to settle on its marble surface. The surrounding environment is a mix of sharp, jagged rocks and volcanic terrain, with the sky glowing in twilight hues, adding an infernal glow to the scene.
