Balloon Dragons are so named because they are filled with a gas that makes them almost lighter than air, similar to balloons. However, they are not prone to bursting, as they are covered in tough skin and can deflate themselves if necessary. In addition, they generally are slow moving. They use their gas bladders to float to the tops of trees, where food is more abundant. They can shift their weight from their backs to their fronts, allowing them to reach leaves and fruit.

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.

A cute and bubbly creature, this Balloon Dragoon is called Unslaad Su. She is seen always trying to coax her fellow Balloon Dragon, Okaaz Su, out of the water pools in the cave dwelling so she can play with him among the trees. Of course, her efforts go to waste, and she usually ends up playing with some sort of other dragon. Most of the other dragons tend not to mind her bubbly and childish nature, as she is quite the social butterfly.

Out of most of the rather lazy Balloon Dragons, she is by far the most energetic and social.

As always, SQ has been put at the end of her name as they are her owner's initials. Like all other Balloon Dragons, Su (meaning air in the dragon language) has been put as her last name. She was given 'Unslaad' (meaning limitless in the dragon language) due to how she seems to have no limit to her energy.
