Common Pygmies are sweet in temperament and palate. They spend a fair amount of time foraging for and scavenging food but have a particular fondness for sweet tasting treats, such as honey. When pickings are slim, they can hunt songbirds and small mammals. Common Pygmies stay in large groups, migrating alongside their food supply. Although capable of the same basic vocal sounds of most other dragons, Common Pygmies prefer to communicate through body language. It is perhaps no surprise, then, that Common Pygmy hatchlings are rather affectionate.

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.

Pygmy dragons are the smallest category of dragons, being on the same scale as domesticated animals. They are often found around concentrated populations of dragons, relying on their larger brethren to ward away potential predators and leave scraps. As such, the majority of a pygmy’s diet is scavenged. Due to their tiny size, pygmies do not breed with larger varieties of dragons.

As Ameba is tinier than other pygmy dragons, she has an inferiority complex and often weeps in the corner of her clan's main cave, feeling sorry for herself.

She was abandoned by her parents, and she didn't even receive a name from them, but the eccentric Godly Code that cares for the clan's youngsters dubbed her Ameba, because he thought her to be of insignificant size. This nickname, of course, hasn't helped to raise her self-esteem at all. But at least The Pink Lilly, the clan's female eldest, always mistakes her for a weak hatchling and often looks after her and lets her stay with her whilst the healthy hatchlings are exploited to work for her.
