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.

Gollum spends most of his time lurking in caves and underground tunnels looking for cave pools and rivers to catch fish in. He has become so accustomed to complete darkness that he claims even moonlight makes him uncomfortable.

Even though he seems to be physically genderless, he has dropped a few hints that suggest that he is, at least, mentally considers himself a male. He also seems to think he has at least two personalities, referring to himself as 'we' instead of 'I'. He can occasionally be heard coughing his own name after he speaks.

Many people think he has gone too mad and become too twisted to ever be normal again, but there are a few who still believe that with help and good treatment he can become normal again.
