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.

L'Iyserod was the first dragon the scroll keeper claimed: by extent, he is the oldest. L'Iyserod is intelligent, and some call him the leader of the scroll. He, however, is not fooled, and knows that the scroll keeper holds the real power. He has taught the rest of the dragons that they must stay away from scroll keeper during their occasional mood swings, as these mood swings often result in the death of an egg or hatchling; once, a full grown dragon was driven from the scroll. L'Iyserod also makes sure that no new eggs are laid when the scroll keeper disappears for long periods of time; these eggs always die.

L'Iyserod's wings seem more scented than is usual, even for a Black Tea Dragon. While he enjoys a steady flow of butterflies at mealtimes, he thinks they are quite a nuisance fluttering around his wings all day. He tries his best to stay inside in the summer, as the butterflies don't seem to like caves.
