Sunstone Dragons are named after the orb on their tails, which resembles the gem of the same name. Their social structure resembles a lion pride, with one dominant male and several females banded together with their young. They prefer arid climates where they can blend in and dig for minerals and gemstones that they not only collect, but eat. The more gems they consume, the larger their tail stone grows. They are an aggressive breed; it is not uncommon to see two males battling for mates and territory.

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.

Fronk has a very quirky personality; he always seems to get into mischief. Many of the elders of EG's Cave believe that whenever this dragon is around, it means bad luck because of the scorpion-shaped imprint on this dragon's neck. Because he has been branded with this bad omen, he resolves that he might as well go along with it. Therefore, most of his days are spent playing pranks on other dragons.

Underneath his happy-go-lucky exterior, however, Fronk holds a secret that terrifies him. He has fallen in love with another male dragon named Gerd. Despite his passionate feelings for Gerd that seem to be returned, he is afraid of what the others may think. He does not wish to be ashamed of his feelings. His best friend, Antony, continuously tells him, "Love is love, no matter who it is with. You should never be ashamed of something as beautiful as love." However, Fronk's affections still remain secret.
