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.

Leroy is the speed queen of her family. Her unit is pretty much entirely split off from the main part of the family, with her father, Aves, having had a major disagreement with his brother and her uncle, Macaw. Leroy doesn't really involve herself in family drama, though; this reckless and sporadic Aether has much bigger plans. Leroy loves showing off, especially to other strong Aether. She generally uses air mana to boost her speed, creating heavy bursts of wind that push her forward and allow her to reach unprecedented velocity. Why—to rocket herself horns-first into everything she does. Leroy handles all of her problems the same way: launch into them, winds ripping. She is beyond impulsive, reacting this way the very second she feels a spur of conflict coming on. She'll ambush prey, attack foes, and even just annoy others by tackling them full speed, usually while screaming her full name, "Leroy Airfeather!" It's problematic behavior to be sure, even when her intentions are good.
