Radiant Angel Dragons are known for their intuition—they always seem to know when someone is feeling down, and will do what they can to provide cheer. These dragons are curious and will poke their noses into anything. They communicate with one another by making sounds similar to singing. It is said that the golden feathers shed from their whiskers can rekindle lost feelings of love.

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.

Hesperos is the mate of Merdan, the only Yellow-Crowned in the cave. Well, he's one of the few actual dragons in the cave, due to it being overrun by Vampires. He, along with Anteros, are the only two Holiday dragons on the scroll, and of course Hesperos takes pride in that.

Unlike his fellow Radiant Angel, Hesperos is very outgoing and mighty curious. He greets new faces with a smile, no matter how hostile or intimidating they may be. He certainly lives up to the name of the Radiant Angel dragon.

Hesperos is bold. He isn't fearful of the Vampires, and actually tries to befriend them. He isn't put down when they snap at his attempts, and merely shrugs and tries again later. He enjoys pulling at Anteros' whiskers, gently teasing him about how uptight he is. Even though they are of the same species, the two differ in more ways than they are alike.

He and his mate relish basking in the sun, especially when the last rays are disappearing over the horizon at dusk.
