Heartseeker Dragons are very social creatures that emanate a sweet chocolatey scent. Their captivating perfume easily attracts adult dragons that don’t yet have a mate. Heartseekers use their keen sense of smell to detect solitary dragons and potential mates in the area. By rubbing their fins against objects such as trees and rocks, they leave a scent trail for the other dragons to follow to meet each other. Although these dragons are seen year-round, the scent of a Heartseeker becomes particularly potent during the middle of winter. During this time, a single Heartseeker may play matchmaker to dozens of dragons, but he will also choose a special mate of his own.

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.

Bittersweet Fins, called Bitterfin, is an incredibly anti-social dragon. That's what makes it surprising that he took a mate, a Sunsong named Sssasssha. She was a dragon he tried to pair up with the excess male Sunsongs in the cave. But she fell in love with him and the two became mates. It's odd, since Bitterfin cannot fly and Sssasssha hardly ever leaves the air, but the two love each other. Bitterfin continues to pair up dragons within this cave, with Sssasssha at his side.
