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.

Courageous and smart, Malador is a popular member of the cave, and a favorite mount of Watari's. He loves nothing more than to soar the skies of a stormy evening, like Tondra; however, despite similarity in interests and species, he does not get along well with her. His mate is Nephele, and the two are members of the Storm pack, a group of Gray, Thunder, and Electric dragons that live closely with each other within the cave. He especially close with his full brother, Corax.
