The first order of business is to absorb a soul using the Soul Absorption Ritual. The soul, most likely in Hell, could be rescued by performing the Soul Absorption Ritual. The living person would have to recite the incantation Solvo haec phantasmata in terram, et inde ad olympum (Latin for Free this, the images in the earth, and from thence to the Olympus), while slicing into his forearm to release the soul. The soul, now formless, ascends to Heaven.
