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.

Rartillith is the smallest, but also most adventurous of the first four dragons in the cave (Rartillith, Terronith, Athelium, and Zarchelum). She was the one who actually discovered the cave, hidden behind thick vines. Her curiosity got the best of her and she cut them down, revealing the cave that the dragons reside in now. Despite being much older now, she still enjoys an adventure, and will often wander off far from the cave, coming back much later, with stories of the new and exciting things that she saw.
