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.

Luny is one of The Five Elders raised by jadeliller who offers advice and helps the younger dragons. He is often seen by the others as the crazy uncle who has wild stories that just happen to be true. He occasionally takes in hatchlings to train. Most of his time is spent with his clan and clan mates, whom he is the Patriarch of. He is devoted to his mate Serene. He is often seen with her, and rarely are they apart for a long period of time. He often gets into fights with Ezeck due to their clashing personalities. This rivalry of sorts can be traced back to when they were hatchlings.

He loves Eucalyptus.
