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.

Rav'irel is one of her master (Edeva)'s favorite dragons. According to ENISAD Legend, during a time of great darkness for the ENISAD People, she gave them Light via her Lightning. This was also the moment when Edeva and his dragons first appeared before them, and when the ENISADs started to worship all of them. Due to this, her roar, unlike others' of her species, is in fact an omen of GREAT fortune among the ENISAD. The ENISAD live on a vast amount of land that is the richest in riches of all kinds to the outside world, so outsiders try to buy this land and its resources by offering to give them scales, flames, eggs, etc. from other dragons and say that they are from Edeva's dragons. But the people, even at a young age, are able to truly tell if it is or not just by a single glance; they can even tell what comes from which dragon(s).
