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.

While still unhappy about how he turned out to be one of the "rare" but fragile Neglected dragons, the love and care given to Tamed Deviant during his time as a hatchling and beyond has diminished his rage against the clan master and those unknown people who twisted him into this form.

Death Cheater, a dragon with extensive knowledge of Neglected dragons, serves as his adoptive parent. The powerful Magi dragon managed to cater to all the extensive care that Tamed Deviant's fragile body and mind required, as well as showering him with great love, shaping him into an unusually optimistic member of his kind.

He is, however, not particularly social, and prefers either staying with those he knows well, or to be left alone to look after the tiny tree that Mage gave him as a gift. As a result, not many in the clan knows of his existence, and for most clan members he is just a myth, which is a state that both he and the clan leadership prefer.
