The tribe of Ullth is a unique race of humanoid-shaped beings who trace their lineage back to mind flayers. They possess strikingly pale skin that glimmers under the light of their planet's twin suns, complemented by cascading black hair that frames their lithe, agile bodies. The planet of Ullth, a breathtaking terraform nestled in the vast expanse of Deep Space, boasts a gravity approximately 2.4 times stronger than that of Earth, its pull both daunting and invigorating. The inhabitants have adapted seamlessly to this intense gravity, moving with surprising grace and strength; however, when they venture beyond their home, they discover themselves imbued with a power that surpasses that of ordinary beings.

In the rigid social hierarchy of Ullth, women are unjustly deemed inferior and are relegated to a life of servitude, enslaved by men under the guise of marriage. Amidst this oppressive environment, the women turn their gaze upward and begin to revere the Elder Evil of Freedom. This marks the dawn of a significant upheaval: a fierce rebellion ignites as the women rise against their oppressors, ultimately leading to the annihilation of the male population. In this tumultuous shift, the Elder Evil of Freedom evolves into a venerated figure known as "The Midwife," who engenders a miraculous transformation, granting the women the ability to reproduce asexually, thus rendering men obsolete.

With their newfound power, cities flourish as the women of Ullth become consumed by an insatiable thirst for territory. They launch relentless raids, traversing the cosmos to pillage and devastate neighboring planets, leaving desolation in their wake. In their mythos, the Midwife gives birth to two compelling entities: The Happy and The Sad. The Happy, a figure of relentless ambition, urges the women to continue their marauding ways, while The Sad, a voice of wisdom, longs for harmony and peace. It comes as no surprise that the fervor of worship leans heavily in favor of The Happy.

The landscape of Ullth is now marked by an imposing divide: The Under City, a labyrinthine realm of shadows and secrets beneath the surface, and The High City, also known as The Holy City, which gleams majestically under the light of the twin suns above. As the golden age of Ullth unfolds, the inhabitants begin to turn their focus inward, cultivating their spirits, sharpening their minds, and strengthening their bodies, moving further away from the bloodshed of the past.

To oversee the burgeoning society, a council is formed to govern both realms, but a significant power imbalance looms—only those from The High City are permitted to hold office, leaving the residents of The Under City marginalized and voiceless. This injustice fuels tensions that boil over, igniting a fierce conflict as The Under City launches a decisive assault on The High City, triggering an all-out feud that threatens to tear their society apart.
