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.

Disashter is most well-known as the author of "1,001 Things NOT To Do (I Know From Experience)." Some of the anecdotes included are fairly obvious, such as "Never play 'the floor is lava' with a magma hatchling." Others are more bizarre, such as "Never sneeze precisely half-way through reciting the incantation to transform linguini into spaghetti-o's." The first question others tend to ask Disashter is whether she really experienced all 1,001 mishaps in the book, and the answer is yes. She has such terrible luck that she is even working on a sequel, tentatively titled, "Another 1,001 Things NOT To Do" because she keeps getting into so many strange and unfortunate situations that she is starting to amass the material for it. Fortunately, she gets enough royalties from her first book that she can afford the medical bills she accrues when things go terribly, terribly wrong.
