Black Tea Dragons have small scent glands on the underside of their wing arm that release a pleasant scent. Though many creatures enjoy being in the vicinity of Black Tea dragons, the scent is intended to draw in swarms of butterflies. Though Black Tea dragons are full sized dragons, these insects are the mainstay of their diet.

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.

Duke is a strong and silent type of dragon. He doesn't talk much and whenever he does, it is usually to get other conversations back on topic or to help others sort their lives out. Many dragons are jealous of Duke's muscled appearance, since he was born with a very healthy body. The Black Tea Dragon, however, has taken up the habit that a few humans have, using certain types of plants to roll into cylinders and then setting them on fire, inhaling and exhaling the smoke that comes off them. He also craves the taste of alcoholic beverages, spending a lot of his nights near human taverns and bars. These habits have started to cause Duke to cough a lot, making the dragons around him wince at how rough he sounds.

The Black Tea Dragon hangs out with a group of five other dragons; he's been friends with them from the very beginning of his life.

Duke has a very flexible neck. He sometimes entertains young hatchlings, turning his head to the side and singing small rhymes off key.
