Standard NPC take on the Great Work

"The materials required for the creation of the homunculus include human semen, a cow or ewe and animal blood, whilst the process includes the artificial insemination of the cow / ewe, smearing the inseminated animal’s genitals with the blood of another animal, and feeding it exclusively on the blood of another animal. The pregnant animal would eventually give birth to an unformed substance, which would then be places in a powder made of ground sunstone (a mystical phosphorescent elixir), sulphur, magnet, green tutia (a sulphate of iron) and the sap of a white willow. When the blob starts growing human skin, it would be required to be placed in a large glass or lead container for three days. After that, it has to be fed with the blood of its decapitated mother for seven days before becoming a fully-formed homunculus."

subject surrounded by personal history to which the author's ego attaches in self destructive ways.
