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.

Auriga is the pinnacle of draconic majesty and mystery. Like all Stratos Dragons, he never leaves the sky, eating, sleeping, and living high up in the clouds. He doesn't usually speak to or commune with other breeds on the ground, but cares deeply for the dragons living on the island he circles, so watches over them, protecting them from threats above. Due to his quiet demeanor and avoidant actions, many see Auriga as pompous and too good for everyone around him, but, truly, he just has no real social skills and gets too nervous in conversation. He just doesn't want to say or do anything wrong, so just doesn't even try in the first place. He is a truly kind and empathetic dragon. He feels for others and their pain and so tries to support them by protecting their home. He hopes to one day get over his anxieties and face the dragons he watches over, but he can never seem to muster the courage. There are at least a few other sky dragons willing to give him a chance and support him back.
