Copper Dragons are masters of stealth, slipping silently and swiftly through the forests and jungles where they live. Often hunting in groups, their prey rarely know they are being stalked until the dragon’s at their throat. In the air they are agile and skilled. Copper Dragons prize family groups, spending large amounts of time teaching their young skills. So great is their love of life and family that they will sometimes adopt orphaned dragons of other breeds to raise.

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.

There is little mystery where Endless Energy's name originates. Although long since grown to adulthood, she has the boundless enthusiasm of a hatchling. Too dignified to bounce around and squeal, Endless is not so much hyperactive in the usual sense as she is indefatigable. That is, she isn't the sort of dragon that careens around the cave out of control—rather, she just never seems to rest, always being involved in exploring or food-seeking or some other activity. The first wild-born rainbow copper at the Breedery, there are other coppers around, but she does not socialize much, and tends to be quiet and self-effacing when around other dragons, especially those that are larger and older. Endless prefers to stick to her own business, as a rule, though sometimes she can be found perching with Heartsblood high atop the Breedery's tallest spire, or browsing in the garden with Collard Bellpepper.
