Worgrads are small desert-dwelling creatures that subsist on a diet of insects, light rays, and gusts of desert wind. They are very small, with large, black eyes and soft, sandy-colored fur that feels like sandpaper. Worgrads live in small burrows, consisting of large, open rooms connected by winding tunnels, which they build themselves out of desert sand, clay, and plant matter. They spend most of their day sleeping, but they are very active at night, and can sometimes be heard climbing across the ceilings of their burrows making mysterious clicking noises.
