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.

Barroom's cave is in section 12 of Iudly Beach. He earns fresh water and pasta picking up trash and recording pinniped numbers, and he has a commendable collection of silver bivalve shells. He doesn't socialize much because a lot of dragons, even much bigger ones, are a bit scared of him because he has an angry face. He is not actually that angry, though he's known to be easily spurred into a tirade on the topic of doors. Humans around here call him Barroom because he first made himself known among them by showing up to a gathering on Iudly Beach wearing a gaiter-like garment with a wooden tag labeled "Barroom", which suggested that is his name. Meanwhile, the Groygon Barroom's mantel sign was recently stolen, and one of the proprietors was coincidentally at this beach gathering and was about to ask this black capped teimarr about his accessory, but she changed her mind at the last second because of his frightening visage and sharp horns.
