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.

Miss Sif considers herself to be a cultured and polite lady of the very highest quality. Even as she bobs and twists in the sky to deliver a crushing blow to her opponent, she takes the time to stop and say 'excuse me'. Even as she electrocutes her sparring partners to a twitching and blubbering mass of jelly, she can't help but say sorry. Miss Sif is a refined lady, after all.
