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.

Float is one of the more chill Atmoswing siblings. Most of the time, she just lazily lays in the sky and lets the wind carry her around. Float is a carefree Stratos, unbothered by all about her. Most of the time, if someone tries to speak to her, she just completely ignores them. She is not very subtle. She is the second biggest in her family, next to her sister, Oxygen, but this size does help in warding others off. With how often she just falls asleep mid-air, it can be legitimately dangerous to be around her since, at any moment, she can swerve and knock others right out of the sky. It's happened before, and she doesn't seem to care. "They were the ones who got too close", she argues. Definitely not a popular Atmoswing, if that was not apparent.
