Frilled Dragons are smaller than most other breeds, but when threatened, they stretch out their wings and frills to appear larger. They generally do not like to fight and prefer hiding to confrontation. Frilled dragons live in small groups and often band together to scare off potential threats. Males also use their frills as a way to attract mates, with those displaying the “best” frills being more likely to breed.

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.

Tesnit and Telsiu aren't twins, but might as well be.  They look alike, act alike, and do everything together, and even their parents have trouble telling them apart.  Of the two, Tesnit tends to be more passive, preferring to follow Telsiu's lead, but no less active in causing mischief than her partner-in-crime.  Tesnit never really stopped being a hatchling, and spends most of her time playing with Telsiu and with the frozen hatchlings Haralk, Hyskeg, and Jaspec.  Like the rest of the frills in the Frill Exhibit, Tesnit was rendered infertile by the sterility plague, but like Telsiu seems more interested in playing with Haralk and the others than in caring for them.
