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.

Nicknamed Venom by her mother, Venom of the Poisonous Claw was named after her famous ancestor, Venom's Poisonous Wrath. Venom does not know her father or if she has any siblings, but she remembers her mother from when she was a young egg. After her egg was touched by a human, Venom's mother abandoned her at the entrance of a cave, with a pile of other eggs. She is sometimes nicknamed "The Lone Wanderer" because she doesn't travel or live in large groups—She prefers to live alone.
