Black Capped Teimarr are a small and sociable breed of dragon with an appetite for seafood. They can commonly be seen flitting around sand dunes and tidal marshes, searching for crabs and other aquatic invertebrates, or cavorting in tidal pools in hopes of finding landlocked fish. Because of their large wing-to-body size, they are excellent long distance fliers and are known to migrate hundreds of miles along coastlines, or even across open sea to outlying islands in search of seasonal delicacies such as bird eggs, fledglings and schooling bait fish. The males are easily distinguished by their large jousting horns and their extendable neck frill, which they show off to the females through enthusiastic head bobbing.

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.

As the eldest full-sized female dragon of the colony, Quicksilvi was the colony's queen. She ruled alongside Sunfyr, the colony's king. Quicksilvi was pretty laid back, though, for a queen, and Sunfyr often got frustrated with her decisions. Quicksilvi did not love Sunfyr; he was too stressed out all the time. In the end, Quicksilvi decided to renounce her position as queen.

She holds a strong belief that the future lies in the youth of the colony, so while she is not frolicking in rivers, she makes sure that every hatchling is cared for. Quicksilvi is especially attentive to her own offspring.

She has a brother and a sister—Pfuff and Melays.
