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.

Hearts Blood is more or less the bigger male between himself and Heart. He isn't exactly more "brutal" or "tough", he's just very protective of his mate and any hatchlings they take in. Both dragons sought refuge from humans within the Cave of Doom and have been amongst the others for quite some time helping with the hatchlings and such. Hearts Blood has a special gift, he can turn plain fruit into a sugary treat using his magic to spin sugar. The hatchlings love him for it as does Heart.
