Nebula Dragons are nocturnal creatures. With the best eyesight to be found, they are often seen staring into space. Each dragon tends to observe a particular nebula and will eventually change their colors and patterns to match it. As the nebula changes over time, the dragon changes with it. The more intricate the design of the nebula, the better chance an individual has of attracting a mate. It is said that the markings on no two Nebula Dragons will be exactly the same.

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.

Wish was once approached by a young human girl who asked him to please help her to find her true love. The dragon was naturally confused until the girl told him all about her village's belief that one only had to wish upon a star to make it come true. Instead of pointing out that he was just a humble Nebula dragon, not some wish-granting star that came down to Valkemare, and crushing her childish delight, he told her that such a huge wish would take some time and she would have to grow a bit older before he could grant it. The girl left skipping away with a smile on her lips. And Wish spent the next few years observing her and the village working out how to make her find true love. He couldn't disappoint such a sweet innocent creature after all.

In the end it was relatively easy for him to find out when she fancied the local blacksmith's apprentice, that the boy had a good heart, and poking the two young humans into the right direction, thereby keeping his promise.
