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.

Umi keeps a careful eye on the freshwater streams that crisscross the forest, paying attention to when clear waters begin to run tainted, and when overflowing streams needs to be diverted. There are a few special streams she maintains to aid travelers crossing through the forest, marked with edible berry bushes and water mana crystals that purify the water as it flows. Should anyone attempt to pollute these waters, Umi will shove them into the water and cause the mana crystals to induce a strong flowing current, flushing out the toxins from the stream and sending the perpetrator far, far out of the forest.
