Ensouled

Ensoulment is the moment at which a human or other being gains a soul. Some belief systems maintain that a soul is newly created within a developing child and others, especially in religions that believe in reincarnation, that the soul is pre-existing and added at a particular stage of development.

When an object is ensouled, a soul is bound to that object via Light magic.

Most living organisms sustain life by first sustaining an Alive effect. These conditions are ideal for sustained ensoulment. Some species grow a piece of its mother's soul. Some capture souls from unwitting prey,  Some pluck a soul from the multiverse. Having the potential for ensoulment is what attracts the closest soul, and binds it, regardless of owner.

Most animated Skeletons are ensouled skeletal remains of a particular species, and contain the original or other soul. However, the Light magic maintains this bond, and Alive is not needed.

Ensoulment can be countered by Void Magic.
