Silver Dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Silver females eat meat only when a male dragon brings it to them as part of courtship, though they are typically highly-independent. They possess an almost magical aura that lights up any place they are in, and are looked upon with awe by humans and animals alike.

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.

This beautiful but oblivious lady is relatively reclusive and quiet, preferring that curious human invention, the book, over the companionship of other dragons. On the rare occasions she strays out of Kad's clan cave, however, she somehow manages to foil her old suitor Lord Tellaver's plots. While Lady Illumine would help dragons she sees in need, she does not intentionally prevent that dragon's nefarious schemes.

The goddess of luck seems to smile on her at crucial moments. Strange things always happen when she leaves the nest, and she moves through life with a vague protecting force—some magic she should not have, perhaps. Lady Illumine has never shown any evidence of extraordinary power, but she is quite lucky. Certainly Lady Kaeda, who seems to lack the usual arcane powers of her breed, is rather suspicious of "that haughty silver girl".
