Despite their great size and strength, Celestial Dragons are a peaceful breed named for their spectral, starry appearance. Little else is known about them, as they spend the vast majority of their lives partially phased out of the plane of existence through the use of powerful magic. Celestial Dragons are thought to assume their corporeal form only long enough to reproduce or to die; the rest of the time, they resemble living, breathing constellations, impervious to all physical and magical harm.

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.

When her keeper found her as an abandoned egg, she was surprised to see such an uncommon breed just lying around. Her egg was sitting in a patch of sunlight, and looked as if it were a gift from above. Tron isn't as special as she might have seemed as an egg, but like all Celestial Dragons, she can switch between being physical and having a ghost-like appearance. Her keeper is still in awe whenever she sees her.
