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.

Cacao Tine was born into a herd of Heartseekers. From the moment he hatched, he was expected to follow the example of everyone in the herd and play the part of Cupid's Arrow for dragons who had yet to find a mate. As Cacao Tine grew to adulthood, however, he became cynical towards all manner of romantic love, especially when unmated females continued to flock to him, no matter how hard he tried to elude them. He began to doubt romantic love genuinely existed, believing those feelings were only fabricated by fanciful dragons who really just wanted to mate. It was with this mindset that he found himself on the island home of Shield Tail and Dark Drakon's herd. Grateful that none of the unmated dragons on the island desired to find their match, Cacao Tine decided to settle there. However, it wasn't long before he was ironically spotted spending a large amount of time with Venus deDraco.
