Royal Crimson Dragons are so named due to their massive size and confident, regal bearing. Most of the time they are laid back, ignoring non-prey creatures smaller than themselves, although they will occasionally take fresh kills from other dragons as a reminder of their place in the social order. Although there are few other dragons large enough to pose a threat to Royal Crimsons, they have little tolerance for potential rivals and will fiercely defend their territory from such intruders.

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.

Asi was raised among a foreign village of tribal humans known locally as the Sarrakota. She has long outlived the humans who raised her and has had several riders, the current of which is a strong-hearted girl named Timu, who she is very good friends with.

Her and her humans lived in a peaceful valley for generations, until it was ruined by a sudden and explosive volcanic eruption. For months Asi and the few survivors (including Timu) wandered arduously in search of a new home, and finally came across the friendly Clan in which they now reside. The different languages (spoken by only a handful of translators) has made it confusing, but Asi and her people now comfortably make home in their own small land claim in the forests, which Asi will fiercely defend. She doesn't socialize with many dragons in the Clan (as she can hardly speak the local language), but does manage to have a few friends outside her tribe, who know her as honest, hardworking and kind, but easily flustered.
