Shimmer-scale Dragons are a very beautiful breed with small—but highly reflective—scales that shimmer and shine as the dragon moves through water. They don’t have fins or webbed feet, but their long, eel-like bodies allow them to swim quite fast. They were once rumored to carry large pearls in their claws—causing many to seek them out in search of this fabulous treasure. In reality, the “pearl” is of greater value to the dragon, for the fabled treasure is actually an egg carried by a migrating female.

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.

Roran Domiadraumr lives in Leona Lake, near the city of Dras Leona in Alagaesia. He is a free dragon who has never had a Rider, but was named after the cousin of one of the most famous Dragon Riders in history, Eragon Shadeslayer. His last name is derived from the Ancient Language and roughly translates to "Dominance of Dreams", as he was the center of attention in Dras Leona as a hatchling.
