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.

Usins and his brother, Zalktis are twins and as alike as two peas in a pod. Two mischievous and  tricky peas, that is. Like most twins, they seem to have the uncanny ability to sense each other's thoughts allowing them to execute complicated team pranks in almost total silence. They even go so far as to finish each other's sentences. The only way to tell them apart is their wings. While his brother, Zaltkis' wings are torn, his are whole. Still, he seems determined to help his brother repay his "debt" to Irpa. For some odd reason, Usins seems to annoy Irpa in a way Zalktis can't.

Usins is maned for the Latvian god of horses, bees, and light.
