Perhaps among the most venerated of dragon breeds is the Zyumorph, a breed whose selfless heroism and strong moral compass are nearly unparalleled by other dragons. Zyumorphs have an innate urge to fend off wrongdoing, and as such, are often sought after in times of peril. Although they are independently quite capable fighters, it is said that their true might is not unlocked until all six Zyumorphs are brought together in times of great duress.

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.

Prohibitory is a busy dragon, and not too pleased about it. Something's always wrong with the world. Someone always needs her or her siblings' help. Sometimes she's called to a location with strife, but it's strife that they could handle on their own if they were diligent and willing to make sacrifices. The other five zyumorphs have tried to convince her to delegate among their loyal followers, but she thinks they won't do a good job and it'll be up to her to fix their errors. Of the zyumorphs, Prohibitory is probably the dourest and has the dimmest view of other sentient creatures. She does, however, enjoy the praise and the delectable offerings laid out for her by the communities she aids. Rarely, people will also leave a living suitor on the vined dais dedicated to her in hopes she'll bestow them an offspring. She enjoys that, too, especially when he's strong in his moral convictions and has excellent stamina.
