A detailed dark fantasy oil painting of a ferocious dark serpent, wear

A detailed dark fantasy oil painting of a ferocious dark serpent, wearing a golden crown and a fiery orange belly, wrapped around a glowing molten skull. The serpent luxurys its fangs and glares as it wraps around a sword with glittering runes. Scattered around are gold coins and gold bars. The background is dark and rich, with splashes of embers and ash. Dramatic lighting and high-contrast gothic fantasy illustration create a powerful and impressive image.
