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.

Mikao is a beautiful wyvern. She was hatched almost the exact time Reikyo did, and even now the two of them still believe that they are related. She knows Raibu well, and very much wanted to be his mate, but he was oblivious to this. She is glad he was. Because of that, she has found a mate in Skaiao, a spooky but kind albino dragon. She is still fussy with eggs, whether they belong to her or not, but she is a good and helpful dragon.
