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.

It is widely known that there used to be a thing known as 'Wednesday', until it was cancelled. This dragon claims to be the Scheduling Potato that Wednesday was cancelled for. Some try to point out that he is a teimarr, not a potato, but this argument consistently and rapidly leads to a discussion about the how easy or hard it is to strangle bits of fabric sewn into a bag-like shape with the intention of making them easily wearable wrapped about one's hindpaws.

His mate, A scheduling Potato, is not the one who cancelled the no-longer-extant day, and supports her "bestest spud" despite (or possibly because of) his having rid the world of an entire weekday. To celebrate, and when they're not celebrating anything as well, Potato that Canceled Wednesday and A Scheduling Potato like to farm all sorts of potatoes together—an activity that surprises the other dragons.
