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.

Penny Rentis decided to follow Kirannar's lead and become a part of the Royal Menagerie, but used a different technique.  Kirannar had befriended a dragonkeeper, but after observing Aubrinth, Penny decided to pretend she was one of the dragons allowed to interact with people.  When the dragonkeepers found out what she was doing, they had her quarantined, to make sure she wasn't rabid or otherwise sick.  When Penny turned out to be healthy, they added her to Kirannar's enclosure and eventually—with human supervision—allowed her to interact with Royal Menagerie visitors.  While other pygmy dragons may come and go (under the cover of darkness, so that the people in charge of the Royal Menagerie don't figure out that the Pygmy Enclosure has no magical shielding), Penny is a permanent resident—she likes the attention she gets too much to even consider leaving.
