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.

Mightea was apparently named as such by the scroll-bearer due to her somewhat mighty nature. She will valiantly venture with the human through the deserts while attracting any creatures around her, big and small. She is never afraid to be close around other large, aggressive dragons; she would sometimes show her defensive side when anyone tries to threaten her caretaker. Mightea could not be convinced to follow the human through other areas such as the forests of Galsreim, so he would occasionally bring a few species of butterflies from around Galsreim for her to devour. Every now and then, Mightea will release what is known as "Black Tea Scents" to attract butterfly meals. When she's alone, she hopes that her scent would attract the scroll-bearer from his adventures.
