Silver Dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Male Silvers hunt and eat meat. While not as beautiful or radiant as females, silver males possess better physical attributes, such as strength.

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.

Cold Mirror is cursed. He was exploring when a strange enchanted mirror bound him to it, and he now obsessively cleans it, hidden in the ancient castle it came from, within a deep dark forest. Starlight and Lumina or Dark Lumina scales are the only things that can let him look away... as long as they are reflected in the mirror.

The curse leaves him unable to hunt for himself, so Sonata of the Stars uses his wings to allow Cold Mirror to eat when the Nebula brings food. Dark Shine and Light Shine also visit him on days when Sonata cannot bring food.

Sonata often has long conversations with him that he forgets as soon as he looks into the mirror, and the mirror then nags him with scraps of those memories. It whispers false promises to him that he'll remember what he has lost. However, he never remembers.
