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.

Heart-Shaped Pizza's favorite holiday is the Egg Festival in springtime, but Valentine is a close second. She saves up nonperishable resources and carefully collects perishable ones in large amounts to turn into baked savory tomato sauce cheese flat pie. She used to do this for the Festival until her peers convinced her that the red sauce of the dish seemed more thematically appropriate for V-Day. Now her pies are not oval but formed into the shape of one of the many bright markings along her body. Her neighbors have learned a long time ago that she's responsible for the theft of a smallish amount of herbs, flour, olive oil, and sugar from the underground storerooms every February, but most dragons in the network don't mind since she always returns the ingredients, cooked. Heart-Shaped Pizza doesn't have a name for her specialty dish, though everyone says she should come up with one because "baked savory tomato sauce cheese flat pie" is nicely descriptive but kind of long.
