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.

4xema is one of the eldest Heartseeker dragons, yet his name remains largely a mystery. The truth is, nobody actually knows his real name. Under the alias of '4xema', he is one of the greatest matchmakers, however he has not had a match of his own for quite a while. Legend has it that in his youth he met a wonderful dragon named Xema, and fell in love. Some ill fate befell her, and in these years '4xema' retreated from the world, his depression overwhelming him. The world largely forgot him. But one day he reappeared, with renewed vigor, under the alias "4xema". For Xema. 4xema hints his story to the population of Rain Goddess Sanctuary, however he pledges to never reveal his older, given name. Because, in his words, "nothing mattered before I met Xema."
