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.

Sebastian is a son of Tenshi and Aimi, making him part of the Angels family. He is an adorable Sweetling, who is very lively and charismatic. He's friends with most of the dragons in the colony, who all love him for his sparkling personality. His favorite treat is cake, a rather difficult to obtain treat, as he has to get Remy to bake one for him. Which actually isn't that difficult, since she (like most of the colony's inhabitants) finds Sebastian to be adorable, and therefore worthy of cake.
