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.

Sicko is a neglected who is extremely feminine and extremely forgetful. It's like he doesn't have any memory, but he still has basic needs. His eyes are dull. Because he is forgetful, he doesn't acknowledge what's in front of him for a minute after he sees something. He also doesn't understand many things that are even just a bit complicated. He is described as crazy in some elder stories. Whenever dragons see him in a distance, they all walk away, which means he is lonely and sad all the time. His mate is The Mosa, though they are unable to have children. His sister is trying to fix him, but nothing works.
