Orgone is the natural life energy of the cosmos and the lifeforce which allows the body to function. It is used to perform spells, and constantly regenerates after use at different rates for an individual. Orgone can also be used with other materials to create familiars, translucent creatures that act as servants. These familiars represent a reflection of the person's soul, and vary in size and shape. However, the materials needed to create these creatures are rare and expensive. Even after they have been gathered, the ritual is difficult to perform. There is however, an alternative to this method: the use of a soul that hasn't been completely formed.
During the third trimester, a witch can use a ritual which aborts her pregnancy and uses the remains of the resonant soul to form a mystical unbornbotchling. These pitiful creatures are malformed, misshapen fetuses made with half a soul. They are caught in an intangible state between life and death which float and hover over their creator, and serve as spies and counselors. A mystical unbornbotchling is bound to the witch and cannot stray more than 100 yards from them. They can turn invisible at will and cannot be affected by anything on the physical plane.
The spell causes no damage to the witch physically or biologically. However, the witch is unable to have more children mystically, and only one of these creatures can be created during a lifetime. How can this be the case?
