Part mortal, part something else, the planetouched are loners and individuals, rarely so lucky as to meet another of their kind. The origins of the various kinds of planetouched races are as different as the forms of the planetouched themselves. In Calimshan, djinn and efreet sometimes mated with their human slaves, producing offspring whose children are air or fire genasi. In Mulhorand and Unther, the undying incarnations of the deities had children with favored humans, creating strains of aasimar and tieflings. In the High Forest, evil sun elves bred with succubi to produce the fey'ri. The planetouched races have no common history, although planetouched of the same type from the same region often have a common ancestor or relation.
      The child of an outsider and another creature is a half-fiend, half-celestial, or half-elemental. If one of these half-blooded creatures has offspring with a humanoid, the result is usually a planetouched creature. The offspring of two planetouched is always a planetouched. Mixed-heritage planetouched of this sort take after one or the other parent (seemingly equal chances) but carry the traits of the other parent, which may show up in their own children. The offspring of a planetouched and a normal creature of its type (such as the child of a fey'ri and an elf) has an equal chance of being planetouched or "normal," but carries the potential for planetouched children in either case. Sometimes the outsider bloodline becomes dormant for one or more generations, only to manifest many years later.
