Consecration was the magical act of burying a dead witch so their soul may join the Ancestral Plane. By carrying this out, their magic flowed back into the Earth, fueling the witch community.
As seen occasionally, the process was very complicated and the body of the witch that was being consecrated had to be dressed in white. Rose petals would then be thrown over the body and it would be sprayed with what appeared to be blessed water. Upon the end of the ritual, the soul of the consecrated witch would join the Ancestors in a limbo-like dimension and their power would flow into the earth, fueling the community. With the destruction of the tether between the Ancestral Plane and the community of New Orleans — thereby eliminating Ancestral magic — consecration is no longer a viable method to fuel magical practice.
