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.

While thunder dragons can often be seen with the coming of a storm, this elusive creature makes his appearance only when the tempest will be one of exceeding power. Accordingly, the sight of him has earned association with the coming of death and devastation, and to see the dragon is to be cursed with misfortune. If he is aware of his forbidding effect on those clustered below, he makes no sign of it; he merely wheels amidst the screaming winds and cracking lightning, his haunting cries echoing away into the clouds and sending tremors through any poor wretch who hears them.
