Naissance is the creation of a Nascent Soul within a Sophont via Auric Impression.
If one Sophont with a Soul has a strong emotional reaction to proximal Sophont without a soul, while casting a spell at them, this will trigger Naissance.
If the Sophont already has a soul stored in another location, such as in a Phylactery, this will trigger Auric Feedback and will result in Soul Sickness.
A simple but very powerful article. I love that it requires both emotion and magic.
