Sweetlings are a small, flightless breed of dragon. They are omnivores who favor sweet fruits and honey, and have been known to go to great lengths to obtain their favorite treats. Their long, prehensile tails allow them to grab onto branches and give them superior balance. Sweetlings are expressive dragons and have a large array of calls to communicate with others. They become very vocal during breeding season and sing long, beautiful melodies to attract a mate. Inquisitive in nature, Sweetlings are known to investigate anything that piques their interest, and are quick to flee if the object of their curiosity strikes back.

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.

Sweetling Solo works as a city rules officer in Ingschlinkuifen, where he reminds to-be rulebreakers of the rules and issues fines to those who've already broken them. Most of the fines he hands out are for illegal parking and littering. During certain holidays, many of his colleagues take the day off or are a lot more easygoing to every inhabitant. Around Valentine's, everybody is so lovey-dovey and they keep talking about stuff like family bonds and kindness. Not so for Sweetling Solo! He's a Solo man. He is not any nicer to rulebreakers on Valentine's and is just as diligent about his work and patrols as attentively as usual. When the statistics are compiled by Aqualophyne Astralophyne at the end of the month, that is evident. While all of the other officers' sheets show a dip in law enforcement activity during a certain week of February, Sweetling Solo has spent Valentine's handing out Valen-fines.
