Named after their cloudy, ashen scales, Ash Dragons are large, gentle beasts, although their faces can give unaccustomed folk a fright. Their tough scales and sheer size make them infrequent attack targets, traits that explain why pygmy dragons and other small dragon breeds can often be seen riding on their backs, hiding amongst their large spiked scales. Though they tend to be mostly quiet, Ash dragons have a low, deep roar that is typically only used to threaten or call to others of their kind.

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.

More timid and shy than Finlay, Ashleyn is the second oldest Ash Dragon within Biscuit's rapidly growing cave population. Ashleyn wasn't even hatched by Biscuit, but was instead a gift to keep Finlay company. With her timid nature, she does not at all fit her intimidating appearance. Ashleyn also has a deep love for hatchlings and hopes to be a mother someday.
