Grumblegard is a large dragon with a burnt orange back that shades into a greenish-cream shade, and finally into a light cream on his underside. He has some white tendrils on his back jaw that have the impression of beard scruff. Grumblegard's legs are socked in a sea foam green color, as well as his wing bones. His hide is somewhat grooved and wrinkly - it is unknown if this is characteristic of his species or a sign of a great age. He also has some holes in his wing membranes
