Valentine eggs are only seen once a year. Adults’ mating seasons are very short, usually spanning a few weeks in the mid-to-late winter. These dragons were once reputed to be omens of good luck in love.

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.

Those unlucky in love blame Valentine—who wouldn't, as she plays with one's emotions like a cat with a ball of string. One day a couple will be desperately in love, the next refusing to even see each other and few would suspect a valentine dragon to be stopping love. Sometimes a love-struck female will find a note from her crush on her pillow, but upon confessing her love finding it to be only a cruel prank, while Valentine's enemies find themselves alone in the field of love, for no dragon sane would mate with someone rejected by a valentine dragon. Those who happily found love had no complaint with Valentine's decisions, and those who did were those she had doomed to never find love, who everyone assumed was just jealously. Valentine herself found love in Fflam, a hellfire who finds her deceit just as amusing, and revels in his power over other's love life.
