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.

As the first of the rare, bizarre and truly terrifying Zombie dragons to be spotted near Preto Osso's weyr, First Undeath can be found deep in the wilds, mindlessly dragging what's left of her tattered body at a snail's pace towards the main cave.

How First met her gruesome end is unknown to all but herself -- if she possesses the sentience to think about it at all that is, which seems nigh impossible.  Still seemingly flaunting the fury of the Storm that she once was, to glimpse her rearing back on her trembling, mostly-fleshless hind legs, flaring her moldy and decaying wings and tearing what little gray skin is left around her mouth as she mimes roaring is both impressive and unspeakably terrifying.

The Vampire dragon, Rottingham, is obsessed with tracking and observing this blissfully rarely-seen ghoul, apparently feeling a certain and disturbing kinship with her.
