Falconiform Wyverns are normally shy creatures. However, when approached, they often feel threatened, and the flames along their bodies leap higher. Females tend to be smaller than males, though Falconiform Wyverns are typically rather large overall. They use their size to their advantage by hunting smaller dragons. The Falconiform’s graceful, swooping dives are said to resemble birds of prey. Falconiforms are largely solitary dragons that only meet in order 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.

Xuo is a rude and territorial creature who fiercely protects his claim of land in an area of black volcanic rocks. He'll usually excuse small intrusions, but will angrily threaten those who wander too deep into the heart of his land; ironically he hates fighting, and usually prefers to just bluff using his vibrant flames.

He is known for being savage but benevolent, and as he lives in a rather remote part of the Clan it's not unheard of for his neighbors to come to him for help (though they'll get quite a scare first, only to earn his trust as he realizes why they've come). Nonetheless, he has a natural distaste for his Clan's authority and tends to avoid nobles who pass by.
