In the bible creation story, Eve was manipulated by Satan into eating from the tree of life and then tempted Adam into sin. As punishment for helping introduce original sin into the world, God declared that she would bleed every month and that her female offspring will experience great pain during childbirth. Since myths are used by society to explain the world around them, I would like to do an equivalent story in which it was man who first sinned and was punished for it in some way.
God made man and woman separately, with woman being made first. He then gave them the ability to access magic as a gift to show his favor.This magic was slow, complex, and ritualized. However, it was very powerful, able to shape the world to suit their image. Both man and woman set out creating the animal and plant species of the world, naming them, and then basically designing the world around them. However, man committed some vile act that created much calamity into the world and became responsible for introducing sin into humankind. As a result, God stripped man of his access to magic, and his male descendents are forced to carry the shame of his sin throughout their lives by performing penance until they can be redeemed in the hereafter. Women remained able to utilize magic. Magic is the basis of technology and used in everyday life. Magi tech is used by everyone, but only women can create it. They do not experience pain during birth, and it is described as an almost euphoric process.
This myth is meant to explain the dominance of women in this world. Having access to magic is a sign of gods favor. Being stripped of magic is not a "noticeable" in the same way that periods or pain in childbirth are, seeing as those can be seen by the populace. What is the best way to make this punishment for males more "visual"?
