This breed of dragon results from eggs or hatchlings that have been neglected. They are usually rebellious, not obeying their masters, sometimes even attacking them. However, their neglect as a hatchling leaves them crippled, and they are weak compared to other breeds, causing them to stay with their masters for protection.

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.

Where they got it, no one knows, but once upon a time a group of chickens rolled a big dragon egg into their headquarters. Another one of their evil plans, of course. These so-called Space Chickens were getting frustrated about the lack of progress of their conquest. Dragons are their mortal enemies, but surely such a young and vulnerable one could be manipulated and molded into working for them... After having stuck the egg in a cold and quiet corner, they completely ignored it for a long while, starving it of all the warmth and motherly affection an unborn hatchling needs to grow. Then suddenly they all set to brooding it, hatching the egg in an unhealthy short timespan. It worked, the hatchling lived, but how ill-looking and crippled it was!

The chickens were so happy with their first success, they were able to create three more of these green dragons.  The chickens can often be seen perched on Oneiropotos' back, with a birds eye view, spying on the other dragons.
