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.

Tolsir was the first, the one who started the pack of the Dragon-Hybrid's dragons. She can be quite headstrong and come off as sarcastic to others, but to the others in the pack, she's just a big sister trying their best to protect them. She came from a family on the coast that abandoned her egg after a tsunami, not being able to care for her as they tried to repair their home and themselves. Found by the Dragon-Hybrid she was given another chance to grow and prosper and now is the bridge to what started the pack of dragons that are now family, despite being of so many different origins and species.
