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.

Nightrose is a special kind of valentine dragon; he uses his candy to kill.

Nightrose loves to hang around, collecting ingredients for his famous Rose-red chocolate bars. However, after Nightrose's first night in the cave, other hatchlings mysteriously became ill. This is because Nightrose sneaks deadly poisons into his candy. He says that his breed is immune to the poison, thus he uses it to sweeten his chocolate treats, not caring that the others will go through terrible pain if they eat it. He also claims that he is not trying to harm the hatchlings. Contradicting this claim, Nightrose keeps a record of his kills by scratching tally marks into the wall of the cave. As the tally marks rise, more dragons beg his owner, Aquenee, to kick Nightrose out of the cave. However, she refuses to release him, as Nightrose is one of her favorite dragons.
