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.

Tanganyika is a feisty dragon with a high penchant for stubbornness. She is discourteous and very loud, often barging into other dragons' conversations simply to report pieces of trivial information before soaring off again. She considers herself to be an aerial virtuoso, and she loves to show of her skill in the sky to her fellow dragons. She is known to vanish for hours upon end, and most dragons assume she is exploring. Most of the time, she is doing exactly that, though every so often when she sneaks away she finds herself sneaking after a certain member of the Lumi Clan, namely Lumikkja's Shadow Walker Laurentian. Tanganyika is determined to earn his attention and affection, since she sees him as one of great mysteries of the Lumi Clan, with his reclusive-ness and downright weird ways of thinking. Laurentian, on the other hand, doesn't actually know that she fancies him, and if he ever caught her sneaking after him, he would most likely think of her as a slightly loony stalker.
