Seasonal Dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

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.

Serafina was born in the wake of winter when snow had not yet fully embraced the world with her icy arms and trees still mourned their last orange leaves. Young Serafina had felt deeply how nature's life force slowly faded away under snowflakes as the seasonal transition vibrated into every fiber of her body. Because of that impression, Serafina always fears that eventually the true winter of her life will come, the time when age no longer allows her to wander the earth. Therefore, she has always tried to live her life to the fullest and put her heart into everything she does. Her vigor and passion earns her the name Miner Serafina, which means "burning youth".

Though Serafina needs meat and vegetables to live just like any dragon, her favorite desserts are snowmen. Despite the elders' warning, she often sneaks to human villages to feast on freshly made snowmen until she is full. She enjoys a snowman thoroughly, from every bit of snow on its body to the sweet reddish nose on its face.
