在發光暮光森林中守護遺跡的遠古巨龍

A solitary, ancient dragon with scales like obsidian and eyes like molten gold, perched atop a crumbling, moss-covered ruin in a perpetually twilight forest. Ethereal mist curls around its form, illuminated by bioluminescent flora. The scene is rendered in a detailed digital painting style, reminiscent of dark fantasy concept art with a touch of surrealism, evoking a sense of forgotten power and mystery.
