Silver Dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Male Silvers hunt and eat meat. While not as beautiful or radiant as females, silver males possess better physical attributes, such as strength.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

As a hatchling, Doh was clumsy and made mistakes all the time. In fact, he still does. whenever he does, he would say "D'oh!", hence, his name. His personality is incredibly sweet, and whatever he tried to do is good intentioned. Doh's favorite pastime is hunting with his mate, Screamie, using a rather clever teamwork strategy. Often, Doh would fly high up in the sky, letting the rays of light from the sun hit his scales and make pretty reflections.
