Stratos Dragons resemble sea dragons, but these massive creatures are far too buoyant to swim in the water. Instead, Stratos Dragons use air mana accumulated in their scales to live high up in the skies from the moment they mature enough to leave the ground, only ever returning to the ground in open spaces or very high elevations to lay their eggs. The underside of a Stratos is covered in reflective scales that slowly shift colors throughout the day to mirror the sky and the clouds above, serving as camouflage. Young Stratos consume anything that will fit in their mouths, and are especially drawn to air mana, but adult Stratos are difficult to observe and not much is known about what they eat or where they continue to gain mana. Corpses of grown Stratos dragons have been found with an incredible amount of crystallized light and air mana embedded in their backs, and it is thought that they fly so high up as they would otherwise be a delicacy to many of the more mana-hungry dragon breeds.

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.

The most quiet Atmoswing, probably because he's a mute. For whatever reason, Air has refused to speak for most his entire life. No one is entire sure why this is, but, regardless, he is a pretty decent guy. He is one of the few Atmoswing children not trained under Fuschia. In addition to not speaking, Air has also foregone fighting, even in self-defense. He's usually forgotten among the lineup, even by the lonely Nitrogen, who considers himself the most unremarkable of his siblings. Air will typically drift high above their home island, sometimes next to his father, Auriga, and just watch the dragons below. He seems generally pretty kind and will help those in need when he comes across them, but he usually doesn't go out of his way to interact with others, not even his many siblings. What Air will do, instead of train, is meditate. He practices this every day, night, evening, and morning. Every time his belly plates shift, he'll meditate. The dragons who come across him find it odd.
