Ancient Deep Dragon

Despite their large size, deep dragons were slender and agile, and their snakelike bodies, narrow wings, and thin limbs allowed them to crawl through the tunnels of the Underdark. Their scales were smooth, and in the light, an adult dragon's scales were the color of amethyst, while in the dark, they appeared nearly black. In general, older specimens had much darker scales, while younger ones had more purple or maroon coloration. Older deep dragons were known to develop fungal growths around their heads and necks.
