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.

Since EchoHeart's mate, EchoVoice, spend most of his time in the caverns making echoes, EchoHeart sits with him as well. Instead of making high chirps and croaks like her mate does, EchoHeart sings into the cave. Both of them are always delighted to hear her song come echoing back to them. But a little worried about her mate spending too much time in the caves, EchoHeart tries to fascinate him in other things. So far, only making ripples on the surface of water has captured his interest. But EchoVoice loves EchoHeart with all his heart, and he would change any of his habits for her.
