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.

Heavenly Taboo is daughter to the high-ranking Golden Wyvern 'Heavenly Impact'. Born and raised in her father's care, she is crooned over continuously by the gossiping Lumina Dragons that surround them both. Honouring her prestigious lineage, she's taken names from both parents and combined them to form her own; in case nobody realised, she's a very special dragon, don't you know. In fact most of the dragons DO know, and give her everything her heart desires, for fear of a thunderbolt hurled to their face or, heaven forbid, she lets out a single roar of derision.

Strangely, unlike most Thunder Dragons, she doesn't seem overly keen to become airborne, appearing to be most content on the ground; probably because the other dragons feed her so well and because she's always preened to perfection by the narcissistic Lumina Dragons. This dragon has obviously inherited the fastidiousness of appearance from her father's side.
