Bright-Breasted Wyverns are a breed of dragon easily recognized by their bright red markings. They are a small breed, only the size of a full-grown man. However, they have developed poisonous barbs on their feet to make up for their size. Their coloration is used to warn off potential predators of the danger, and is also used to attract mates. They are very social, and can often be seen preening in large groups.

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.

Midori Nuria was found as an egg by the human girl Ember Nuria high in the foliage of eucalyptus tree. Midori hatched in a bed of leaves made by Ember, and ever since then loved the trees. She would be found shimmying up trees as a hatchling, and would often go up in a tight space so the other, larger, dragons raised by Ember couldn't get her down.  Ember would be full of scrapes she got from getting Midori out of trees from the thorny Kapok tree, to the tallest palm tree, and everything in between. When Midori got too big to climb trees, she compromised by flying from treetop to treetop. One day Midori flew down to see the dragons raised by Flight, Ember's human friend, and she met Norys of the Smallest Blessings. When he found out she loved trees, he gave her a eucalyptus branch.  Midori was immediately taken with him, and she took him around the mountain to all her favorite trees. Midori still lives on the tallest mountain of Elgar with Ember's dragons and visits Norys all the time.
