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.

Koba loves to set up scavenger hunts and other matchmaking events disguised as festival activities. He has a special fascination with using bright, deep red-colored fruits as tokens of affection and arranging meetups by asking his friends to deliver treats to dragons he thinks would make good mates for them. Sometimes his friends foil his plans by just eating the treats instead of delivering them, but unbeknownst to most dragons, Koba has an enormous stash of beautifully-colored seasonal fruits that he's happy to share if he thinks it'll help those close to him find love. Koba believes that something small and sweet is the best kind of gift, and that a perfectly-formed fruit is the best metaphor for love that endures and thrives to become something wonderful.
