Delta Dragons are a small breed with a unique defense mechanism. While lacking a breath weapon or any other formidable powers, they can change their size at will. This allows them to evade predation from much larger creatures by shrinking down so as to be more evasive and harder to see, or to grow to a size that smaller predators will no longer bother them. These dragons live in harsh alpine desert environments and are very hardy. They can go days without water and tolerate a wide range of temperatures. Delta dragons choose a new mate every spring when the weather starts to warm and there is more plentiful rainfall. Together they build a nest out of sandstone on tall cliffs where they leave their eggs to develop without any further parental care.

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.
