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.

Yeyru has a prominent silver cast to his scales, no doubt inherited from his silver ancestors. He doesn't realize that he is very handsome, and is oblivious to the interest females have for him with the exception of Helix Rust. He has been enamored with her since he moved to Nworset City, but doesn't believe he's good enough for her. She is mad for him, though, believing him to be the hero who will save her from the next round of beauty products.

The following poem was written about him by an anonymous poet, presumably one in Nworset City:

Yeyru's head is full of air,

He disowns focus, skill, and care

And while he claims it's all for fun,

He hides his rage from everyone.

In winning games he has no goal

Which makes him lose and takes a toll

Before his goals he is a slave,

Despite his laughter he is grave.
