Nilia Pygmies reside mostly in mountainous regions, tending to live in large flocks. They are a curious, hyperactive breed; their curiosity often gets them into dangerous situations. Despite this, they are wary around other dragons and animals outside their breed. They are naturally shy and seek their own kind for companionship. Once the trust of a Nilia dragon is earned, they are highly loyal critters, sometimes to the point of being annoying.

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.

Yuri Mia is a flexible dragon as she is able to see each situation as unique and can adapt her survival style accordingly. When the mountains on her clan's territory became a hostile place, because ice dragons of her clan began inhabiting it, only a select few clan members could still live there. Because Yuri doesn't have any particular talents, she had to survive with her strategic mind and maturity. Yuri takes responsibility for her own life. She understands that her current circumstances are a result of the decisions she has taken up to now. When something goes wrong, she does not rush to blame others. She can identify what she can do differently the next time and develop a plan to implement these changes. Yuri is not deluded. She knows that success requires effort and patience. She does, though, have an optimistic disposition whereby she believes she can cope with whatever life throws at her. She also believes that there are opportunities out there for her, so she seek them out.
