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.

Red Square was blind since birth. On the bright side, her sense of smell and hearing became sharper than other nebulas'. She could easily sense from a mile away the bowls of goo they spent hours painting on her, but she never scrubbed it off since they liked it so much. Some years ago in October when she had a cold, the dragon wandered away from the main carnival to an empty tent, where a wyvern jumped her. The stranger didn't kill Red Square, but he sniffed and prodded her while she was pinned down, which instilled even more fear in her. He then angrily asked why she had patterns painted on, if she was mocking him in some way because he's all black and can't see. The confusion cleared when Red Square threw him across the tent, shouting that she's blind and her friends painted her. He's a disdainful and snarky nebula, but the two somehow became friends. Some months later, the last of her paint fell off, and Red Square decided to travel with him as a second, blind "magnificent marvel".
