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.

Jaswinder Claribel is a warrior, but of the just sort. She uses her electrical powers wisely, preferring stunning to killing, but her ferocity is feared nonetheless. Jaswinder, whose name means "thunder queen", likes to entertain hatchlings with spectacular shows of thunder and lightning as she soars through stormy clouds, earning her name as they watch in awe. Jaswinder generally shuns males, but recently she has begun to show a curiosity towards them, and male Kallikrates Tempest has become her best friend through adventures and playful banter.
