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.

Quantum Color is an artist. Shortly after hatching he began collecting and arranging coins, pebbles, and flower petals on the floor of Moeru's cave. Later he found ways to place crystals on the walls to create reflected light designs. Quantum Color was given free rein to design all of Moeru's property however he likes.

He is sensitive and selective of his mates, bonding closely with those he has chosen and being reluctant to associate with new dragons.

Like all Shimmer dragons, Quantum Color is fond of water. His current artistic projects involve placing different objects in a shallow stream to see how the colors quiver and change during sunrise and sunset.
