Don’t know who these two are or where they fit into anything, but be assured that somewhere out there there is a burly hexapod blacksmith whose horse part has snow white fur, and who has a little daughter with a wolf’s head. Perhaps they are characters in a fairy tale, but they could fit in just as easily in a magical realist urban fantasy, or any kind of Gothic from the grim to the lighthearted. Remember that a blacksmith, by his very nature, is most of the way to being a wizard, and that prepubescent girls are notorious for their unstable powers. Never take treat this pair casually.
(And yes, his tail should probably be white.)
