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.

Sir Skraa's egg was found abandoned under a pile of ash near a forest fire. Lady Uzra and Sir Hisonun took Sir Skraa under their wings and taught him how to be a nobledragon. Since Lady Uzra and Sir Hisonun are nobledragons of the Draco Allegiance, he is also a nobledragon of the Draco Allegiance.

He is the court painter and paints by using the poison from his own poison barbs and mixes it with pigment for paint. He is the one who paints the royal portraits for himself, and other nobledragons, including King Consort Invisifriend, and Queen Night Owl. He knew he was an abandoned egg until Lady Urza and Sir Hisonun took him under their wing, thus he has unwavering loyalty toward them.

Sir Skraa, like Sir Tzay, doesn't know how to react to the scandal his father, Sir Hisonun, was involved in. He tries to be loyal his father, but it's become increasingly harder when he knows how badly he hurt his mother by mating with another dragon.
