Custom Blood Magic: Ritual

Description: Sometimes the chains of the Aeons reach so deep that they are almost insurmountable, shackling even the mystic essences of the soul such as the akh and sekhem. This long and horrific sorcerous surgery, relying on the principles learned by Heart of Darkness and fundamental principles of other rituals, particularly Emancipation of the Ka, inverts malignant energies influencing a vampire—and only a vampire can survive this process—to undermine and erode even terribly potent shackles on the subject’s will. It is even possible to completely remove the lingering remnants of certain powerful chains if they have been sufficiently weakened. The lector-priest must have the subject somewhere they can perform the ritual securely, as it requires six uninterrupted hours of thanatological surgery.
The lector-priest must have specially-prepared canopic jars, with the four Sons of Horus inscribed on the jars in the opposite directions (Amset on the north jar, Khebsemuf on the east, and so on). The inscriptions are necessary as the lector-priest engages in a further blasphemous subversion and creates lids for each jar with the head of the sha, or Set-animal, instead of the four Sons of Horus. A mixture of tainted perfumes and the target’s vitae is poured into each jar so the organs may be submerged.
The lector-priest opens the body cavity of the subject and isolates the major arteries and veins of the stomach, intestines, lungs, liver, and gall bladder with delicate clamps made of gemstones for the arteries (turquoise, lapis lazuli, carnelian, obsidian) and metals for the veins (silver, tin, iron, bronze – never gold, for gold is the flesh of Ra). After each organ has been isolated from the circulatory system with these clamps, they are surgically removed and placed into the appropriate (by direction, not deity) canopic jars. Over the course of the ritual, they mix with the brews in their jars and dissolve into a kind of sludge. This sludge is poured back into the body cavity and it is sealed. The sludge then diffuses through the body, crawling its way towards the heart (or chest cavity) and brain, where it will dissolve into the flesh of the subject and disrupt the energies of other supernatural influences.
This entire process is deeply agonizing and can potentially kill a subject if they were already seriously injured, but if they have the strength of mind and will to endure it, even monumentally powerful tools used by the Aeons and their agents can be weakened or overthrown.
System: This ritual causes four unsoakable Aggravated wounds and the subject’s subconscious (i.e. the player’s choice) must be willing to receive the benefits of this ritual or it will not work. This is represented by the subject spending a permanent Willpower. This ritual can alleviate madness, subvert oaths, and even more break potent supernatural influences on the subject, including reducing a blood bond by one step or a Vinculum rating by three, potentially removing these bonds entirely if they were low enough. This ritual can even free the subject from the influence of Elder powers (Chain the Psyche, Obedience, etc.).
