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.

Zap-a-Dee-Doo-Dah spends his time among dark storm clouds, hidden within. Many assume him to be a blackguard hiding from justice's eyes, or purely a sociopath, because of this behavior. The accusations are far from an accurate composition of the thunder dragon's moral status. The thunder dragon's reason for his surroundings is stage fright. He enjoys the glorious art of singing, but not when inquisitive eyes are upon him. The obscuring clouds provide excellent seclusion while a storm's rumble hinders anyone searching for the origins of his song. The downside, though, is he doesn't know if he is in tune.
