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.

Thunderquake was named for the power of the storms he summons. It is said that when he summons storms, so much lightning is brought from the sky that it ripples across the ground like tiny earthquakes. Together with his mates Lightningfire and National Pie Day, and a group of gray dragons, he flies around, helping to bring rain to lands in drought. After a hard day's work, Thunderquake enjoys sharing a pie with the current hatchlings in his owner's cave.
