Failed attempts to experiment with magic often result in transforming dragons into these hellish creatures. They are extremely dangerous, and will mindlessly kill any living creature without regard to friend or foe.

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 necrotic dragon is often described as one of the "unlucky ones", or, more to the point, one who was not able to get out of the way fast enough. This creature's mind constantly goes back to that day, that pain, that horrific suffering it had to endure, simply because it was given no warning. No warning as that human's tiny blade came swinging towards it—small as it was, it was enough to down such a ferocious beast and drain its life away. Humans are perhaps more cruel and destructive than dragons can even imagine. This dragon realised too late.
