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.

Matchmaker and Jack of Hearts, the local Heartseeker dragons, have an intense rivalry going on between them.

While Jack of Hearts prefers to set up unusual pairings, eschewing conventional methods, Matchmaker can't abide the thought of using anything less than logic and the complicated collection of details and statistics to set up his matches. He spends many weeks memorising many seemingly insignificant details about the mate-less dragons he has targeted, before spending an entire sleepless week devoted to nothing but laying down trails and scent-traps for his chosen few. While he may devote his attentions to far fewer dragons than Jack in general, they both manage to set up roughly the same amount of pairs.

Matchmaker believes it would be more logical for him and Jack to work together instead of against one another, as he can't deny that they are both skilled Heartseekers. His clumsy, tentative attempts at approaches to Jack have yet to be recognised as friendly, but he is patient.
