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.

Lonely Hearts Circle, even being a Valentine dragon, known for their prowess in romance, can never find a date. He might play the matchmaker for dozens of other dragons, but nobody wants to be with him.

He thinks that if he's too kind, nobody will want to be with him, or, if they do, only want to play him so they can have the "honor" of having mated with a Heartseeker.

He'll sometimes joke about a secret club he has, the Lonely Hearts Circle, what he was named after and what he "leads." It's really just for his own sad entertainment—dreaming that those perfect matches he made really didn't work, and he'll have a new friend in his practically non-existent circle.

Lonely Hearts Circle says that feelings are just like the weather—they'll pass. As with life, as with the clouds in the sky, love will pass.
