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.

With all the Valentine dragons (and a few non-Valentine, wannabe matchmakers) in the clan, it's no wonder that not all arranged matings work out. Or, considering a dragon's average life span, that they will last forever even if they work fine at the start. Most dragons handle this relatively straight-forwardly by simply splitting up. Or in the case of some of the more agressive breeds: literally biting the mate's head off for their trespasses.

Nachbarn thinks the humans have some very modern and interesting approaches to the problem and so decided to become the clan's first draconic divorce lawyer.

Now he tries to gets dragons to set up prenuptial agreements before sharing a lair and a hoard, does interviews with hatchlings to figure out with which parent they want to stay with and so on. And the "biting the head off"-bit has become mostly metaphorical these days.
