AETHERIS: THE WORLD AND ITS PEOPLES

A Comprehensive Guide for All Who Walk the Land

THE GOD-MOTHER AND HER GIFT

The world is the God-Mother's egg. The stars in the sky are her menstruation, the sacred blood that stains the heavens each night. She is the creator of all things, and her greatest gift to her children is magic—a power she bestowed only upon women, the vessels of life.

When a woman reaches her first menstruation, around the age of thirteen, her magic awakens. Her body becomes a reservoir of divine energy, stored within her breasts. The larger the breasts, the more mana she can hold. This is an immutable truth, set by the God-Mother herself. A woman's cup size determines her magical capacity for life—she cannot grow larger through training or effort. She is born with her potential, and she dies with it.

This gift has shaped the world for millennia. It has built empires, toppled kingdoms, and created a society unlike any other.

THE RACES OF AETHERIS

Elves: The first race to emerge from the egg, Elves are the most naturally magical of all peoples. Their women average G-O cup sizes, giving them immense power from birth. Elven men are rare and precious—breeding stock, protected and confined to the enchanted forests. Elven society is rigidly hierarchical, with cup size determining status. They worship Breastianity, the faith that teaches magic comes from the chest.

Humans: The second race, Humans are the most diverse and populous. Their cup sizes range from A-O, with rare instances of P+. Humans envy Elves for their natural power and have spent generations breeding for larger sizes. Human kingdoms are fractured and perpetually at war with each other over dynastic disputes. They also worship Breastianity and have the finest alchemists in the world.

Demons: Born from the God-Mother's shadow, Demons are an all-female race of F-K cups. They have no males and rely on Human noblemen to reproduce—the sperm must come from a man who was birthed from a woman of equal or greater size to the Demon Queen or it cannot survive in a Demon womb. This has caused millennia of war with Humans. Demons are ruled by Queen Irkalla, an O-cup whose goal is to breed a half-Demon heir of immense power.

Dwarves: The third race, Dwarves emerged from the deep stone of mountains. Their women range from D-F cups, but what they lack in size they make up in density and skill. Dwarves are master enchanters, carving runes that hold spells for a thousand years. They worship Vaginatical faith, which teaches that magic comes from the womb, not the chest. This makes them egalitarian—all women are equal regardless of size.

Beastfolk: The most diverse race, Beastfolk are tribal and nomadic. Their cup sizes range from A-F, with some cow-folk reaching K-cup. Beastfolk practice wet-nurse slavery, capturing high-cup women to breed larger sizes into their tribes. They are fractured and fight among themselves constantly, preventing them from becoming a united power. Cow-folk are worshipped as divine.

Dragons: Remnants of the God-Mother's first breath, Dragons are primordial beings of P+ power. They are elemental forces—air, fire, water, earth—rarely seen and rarely understood. They are above the conflicts of mortal races, sleeping for centuries and awakening to judge the world.

THE THREE SECTS

The worship of the God-Mother has splintered into three main sects, each with a different interpretation of her gift.

Vaginaticals: Believe magic starts from the womb, the source of life. All women are equal regardless of chest size. Menstrual blood is the holiest offering. Dominant among Dwarves.

Breastianity: Believe magic is stored in the breasts, and cup size is a direct reflection of divine favor. The clergy is hierarchical: A-C are grunts, D-F are priests, G-K are high priests, L-O are archbishops, and P+ are living saints. Dominant among Humans and Elves.

Asseism: A radical sect that believes magic resides in the whole woman—her soul, her spirit, her will. They reject both womb and breast as false idols. They are small, secretive, and viewed as heretics by both major sects.

THE POTION BASES

Men cannot channel mana, but they can craft magic. Male alchemists brew potions and enchant items using four bases, each sourced from women:

Urine: Easy to collect, produces poor, basic potions.

Menstrual Blood: Common, tithed from women, produces standard potions. Must be preserved properly or its magic decays.

Fluid: Top-tier, requires bringing a woman to . Quality is tied to her euphoria. Collected in specialized brothels, with pregnancy risk.

Milk: Legendary, produced only when a woman carries a female child. Selling milk means robbing the daughter of her magical potential. Rarely sold; most is used to feed the child.

SOCIETY AND CULTURE

Aetheris is a matriarchy. Daughters inherit land and the family name. Women run the government, the military, and the clergy. Men are the working class—craftsmen, alchemists, laborers, and soldiers who wield enchanted weapons but cannot cast spells themselves.

Noble marriage is a political tool. Families seek to marry their daughters to men who will produce female children with large cup sizes. A woman's worth is tied to her chest size, and those with small breasts are limited to lower stations in life, regardless of their intelligence or ambition.

Slavery exists primarily as wet-nurse slavery. Beastfolk are the primary slavers, capturing high-cup mages to breed larger sizes into their tribes. Human kingdoms practice it more discreetly. Enslaved women are valuable property, fed well but watched carefully.

Brothels exist not just for pleasure but for the collection of fluid. The quality of the fluid determines the quality of the potions brewed from it.

THE WORLD AND ITS DANGERS

Human Kingdoms: Breastica (Anglo-Saxon), Titeriana (Mediterranean), Boobstania (Germanic). Fractured and scheming, constantly warring over dynastic disputes.

Elven Kingdom: Niphates (Egyptian), hidden within the enchanted forest. Beautiful, ancient, and deadly to outsiders.

Dwarven Kingdom: Knockholm (Norse), carved into mountain tunnels. A fortress of runes and enchantments.

Demon Capital: Busthanya (Japanese), forged from volcanic obsidian in the harshest regions. No non-Demon has ever returned from it.

Danger Zones: The Fecundus (noxious swamp), Scrovenge Wastes (scorching desert), Clitanni (tallest peak, rumored dragon lair), Cuntylla (turbulent ocean, sea dragon myths).

Monsters: Gonorra (trolls that drain mana via breasts), Herrps (goblins that split from magic), Sylpha (banshees that feed on women), Chlamydian (insects that hunt F-cup+ women), Yeastavia (slimes that swallow all, drawn to mana).

THE CURRENT STATE OF THE WORLD

The world is fraying. The stars bleed red, and the cracks in the world—the Fecundus, the Scrovenge Wastes, and Cuntylla—grow wider with each passing season. Whispers of prophecy speak of the God-Mother's egg hatching. Some believe a new age will dawn. Others believe the world will end.

The Demon-Human war continues unabated, with raids and counter-raids bleeding both sides dry. Humans envy Elves, and Elves look down on Humans. Dwarves keep to their mountains, their Vaginatical faith clashing with the Breastianity of their neighbors. Beastfolk tribes fight among themselves while slavers stalk the borders. Dragons sleep, waiting.

And somewhere, in the shadows, the Asseists gather—heretics who believe that magic is not limited to the body, that all women are truly equal, and that the God-Mother's gift is meant for more than the size of one's chest.

You are born into this world. You carry the weight of its history and the hope of its future. The path before you is uncertain, but it is yours to walk.
