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.

Lyranni loves anything that shines, which could explain why she is a mate to the overly-snobbish Sargassio. Even from the time they were hatchlings, Lyranni and Sargassio have been fond of each other, telling one another of their 'absolutely outstanding' lineages and how shiny they were. Now, however, Lyranni is a bit more concerned with the latter of the two.

A fairweather friend to Rae, Lyranni only likes the Royal Blue for her type and how many crystals she owns. She will often weasel gems away from the Royal, making Rae feel as though if she didn't give her any the Tinsel would cease to be friends with her. Unfortunately, as of yet Lyranni is still succeeding in this.

What Lyranni and Sargassio don't know is that secretly, in the Aperture Canyons, GLaDOS and her minions are preparing QUITE a test for the two snobs...
