Bendith Y Mamau leave behind their own misshapen children, but this simply isn’t the case. Each Bendith Y Mamau is born sterile, the result of the unholy mating of fairy and goblin. What brings fairies and goblins together in such a manner is still a secret known only to the fairies and goblins who have participated in such a distasteful procreation, but it is thus far the only known way to produce one.
The children they leave behind during abductions are changelings, the stillborn infant children of unsuccessful fairy unions. When the conditions are not adequate for proper reproduction, whether it be that the child is born out of season or the mother finds herself in a corrupt place ill-suited for childbirth, it is possible for the pregnancy to self-terminate. In such a case, the stillborn child has a chance of becoming a changeling. If the mother feels a sufficient amount of grief or sheds too many tears upon the corpse, the baby may simply come alive, its energies beginning to feed upon the pain and agony of its mother. Changelings are quite dangerous to anyone responsible for birthing one and must be disposed of as quickly as possible.
However, no fairy mothers, no matter how unseelie, will abandon the product of their wombs to the wilderness. Instead these mothers turn to the Bendith Y Mamau, tasking them with disposing of the changeling and returning with a child that they may raise as their own. Fairies, of course, prefer infant children, but Bendith have been known from time to time to dimwittedly return with a child old enough to speak.
A changeling need only glimpse its predecessor for but a fleeting second as they are being switched to take on its likeness. At that point, imprinting ties the changeling developmentally to the original child. To all but its new mother, the changeling will appear in vision, sound, and action as if it were the child it replaced. Something may seem off or weird about it, but rarely will anyone suspect that this is a doppelganger of any kind. A mother, on the other hand, always knows the difference. By the light of day she has only a feeling, but once the sun has fallen and night overtakes the earth, the changeling’s true nature is revealed. It is that sudden revelation, and the fear it brings, that allows the creature to feed so easily.
A changeling exists solely by feeding off the physical, mental, and emotional pain of its mother. As long as there is agony, torment, or anguish it will be able to nourish itself. But if a mother remains calm, the child begins to starve and then to wail. It will scream, fuss, and throw fits in hopes of driving its mother half to madness. A mother worried about her true birth child or one already suffering from some bout of depression is best suited to feed such a creature, but any suffering mother will do. Unable to digest real food, a changeling may bite at its mother’s breasts or vomit up anything force-fed to it, adding further confusion and worry. Most changelings left in the charge of human parents find themselves smothered, drowned, or exorcised, on the rare occasions when they aren’t just abandoned to die alone.
Adult changelings are incredibly rare, as they are very tricky beings to raise; their need for nourishment is only indefinitely sated by the sacrifice of its new mother to a sudden, violent death. The amount of energy released by such a death, especially one at the behest of the changeling, seems to be the only thing capable of keeping such a child alive until it is old enough to consciously torment other victims.
Changelings possess the ability to change their appearance at will, shrouding themselves in glamour to masquerade as someone they’ve met at least once before, or revealing their true selves to someone other than their mothers. Their natural state appears to be one of twisted mockery of the person they originally replaced. A fully grown changeling will look like an uglier, physically inferior version of their initial counterpart at the same age. Their personalities remain their own, however, and changelings grow up as maladjusted, unusually cruel, hateful creatures who long for nothing more than to make others suffer.
Finally, changelings appear to have some form of eidetic or photographic memory. From the moment they awaken in the body of a stillborn infant, every memory is theirs to keep. It is not uncommon for adult changelings to
