Aether Wyverns have the ability to control winds utilising air mana. During mating season, rival males often attempt to impress females by hanging onto a rock beside the female and letting another Aether Wyvern blast gale-force winds at them. The one to stay on the rock the longest wins, and if the female wins, she will reject both males. These wyverns also use their ability to control winds to blow away intruding dragons or to capture prey, though an Aether Wyvern’s aim is not perfect. As a solution to their imperfect aim, these wyverns will create large winds that often blow away much more than they originally intended to.

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.

Zephyrgale, or once known as Zephyr, lived with other Aether Dragons. She was able to create exceptionally strong winds, thus no one could surpass her in a mating ritual. Her parents became desperate and wanted her to find a mate, but she repeatedly rejected all males trying to court her, because in her words, "they were too weak". She got into an argument with her parents and ran away. She later came across Deltarho, an Aeon Wyvern who was in the Zyumorph Convergentscale's tribe. She joined Convergentscale's tribe, changing her name to Zephyrgale. Later, she found a small tribe which was led by the Aegis Dragon Thunder Crescent. She learned that Thunder Crescent's tribe had been driven out of their home, so she invited them to join Convergentscale's tribe. They happily agreed, and the tribes integrated. Later on, she mated with Thunder Crescent.
