Heartstealing Dragons are an unusual breed, named for their mating rituals. These dragons use their long, slender bodies to sneak into both human and dragon holds to steal things over the year. Then, when the right season hits, they give away their entire hoard as gifts, leaving things in the homes of other dragons to attract them. When these gifts are found, however, the recipients can’t always tell who gave the gifts. This receiver often assumes the source of the gift was the original owner, causing them to form friendly bonds with other dragons in the area, spreading peace—and sometimes even sparking love. The only way to know if a gift is from a Heartstealing Dragon is to find one of their wafer-thin scales at the scene.

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.

That's What You Do and a few Valentine breeds are part of the Singing Valentines, who visit friendly homeowners and denizens to perform a short singing act on a sender's behalf. She is the newest member, who had waffled for a few years before finally joining. She usually has the highest voice in their harmony, what some humans might call a soprano. Occasionally, the person who hired the group will also want to pass on a gift to their audience, but the rest of the Singing Valentines don't quite trust That's What You Do to handle them any more, after an incident one year when she took and lost a couple's fiftieth-anniversary rings. They "somehow" recovered their rings three days later, but the Singing Valentines wished to take no more risks with others' belongings.
