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.

Knockin on Heaven's Door is a very spunky dragon. He likes to bounce around in the forest outside the center, and his favorite fruit is dragon fruit. He plays tail tag with the others, but when push comes to shove he is a very vicious fighter and will fight to the death, But that never happens and you would really have to work hard to get him that mad. Those humans who feed him fruits and give him a pat will be rewarded with a nice dragon friend.
