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.

Navy Strike, an egotistic and spoiled dragon, is a rival to Cloud Friction, an electric dragon. Though Strike often makes fun of Friction for having a daydream for a father, he is really self-conscious about having a daydream as a distant ancestor. He finds daydreams quite feminine and unfit to be dragons, only hanging out with the rare dragons, which he believed were superior.

He does seem to have an interest in Cotton Candy Days, a daydream hatchling who happens to be Cloud Friction's half-brother. Strike claims that he would love to tear the daydream dragon's loyalty away from Friction, but some suspect that there is more to his intentions than meets the eye.
