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.

Bae'flo is the only Balloon Dragon in his family. For this anomaly (his brothers and sisters were all proud dark green dragons), he is shunned from the family. Being amiable to the point of uncaring, Bae accepts this, but mourns the separation from time to time. Bae enjoys filling up then floating along with the wind, letting it take him anywhere, even all the way to Gydion! For this pastime, Bae'flo has a close relationship with Anywhere the Wind Blows, owned by Jesen.
