Thunder Dragons are the masters of electricity. Their wings gather energy as they soar through the clouds, and when they clap their wings together they can create devastating arcs of lightning. They can stay airborne nearly indefinitely, landing only to sleep and breed; they catch their prey from the air and take moisture from the clouds. A thunder dragon’s roar is considered to be an omen of misfortune.

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.

HD comes from a short but proud lineage of holiday dragons. For some reason he came to the conclusion that Thunders were holiday dragons too and their holy day was extra special as it came once a week. He always holds his head high when he joins the rest of the clan on the 4th day of every week and keeps hidden for the rest of the time because he doesn't want them to get too used to his awesome, inspiring presence.
