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.

Grimlock would seem to prove the theory that smaller beings are the more curious ones. If he sees something that interests him or something that he doesn't understand, he immediatly goes up for a closer look. More often than not he comes to regret his actions, but he never, ever learns. Kouryuu always has to keep an eye on him, especially after Gunraku tried to eat him. Being small, Grimlock can also be hurt by just about anything we would call regular sized, even this doesn't daunt him however. Despite having a childish personality, Grimlock is one of the smartest dragons in the cave and can easily offer a solution for a problem.
