Apocalyptic monstergirls

It all happened so fast.

The once bright and blue skies adopted a shade of bloody red. The seas took a more dark tone, as the oceans began rising with every wave, swallowing beaches and ports. The ground was being shaken by massive earthquaked that created giant bottomless cracks all around the land, dragging anything close to them to depths of the earth

Chaos reigned, as the people panicked and ran in every direction, trying to get away from the pits, the rising tides and from the falling buildings.

After some time, the shaking stopped. The people tried to relax, trying to figure out what just happened. Some tried getting to a safe place while others started rescuing and helping the people who got hurt or got trapped under the ruble.

A few of the people let their curiosity get the best of them, and aproached the borders of the giant holes, trying to see what was at the bottom. In the abyss below, there wasn't rocks or even na end to the hole. There was a very deep, and a intense red light was coming out of the bottom, which looked like lava but it didn’t look like it. Some of the bystanders sweared that the walls of that bright descent seemed to be moving.

After some time, one winged creature flew out of the hole, followed by another, and another and another until there was coming a whole armada of flying cratures. They had the apearence of young women with wings for arms, and claws for feet. They flew way into the sky only to return back to the bystanders at a greater velocity. They divebombed against the civilians, while the police and the army tried their best to shoot them down. Some of these creatures just kicked the people into the ground and began harassing them, while others were snatching them to the air and carrying them back into the hole from whence they came.

The population was terrified once more,as they tried running away from the the flying creatures, but the holes began releasing different types of strange monstrosities, as they climbed their way out.

They all appeared to be females,but had little resembleance with humans, as they all came in different shapes and sizes.They were hunting down the people and them on spot, tearing their clothes off as they the humans without mercy.

But it wans’t happening in only one spot. This scenario was happening all around the globe.

Humanity tried to resist, but the attack was so fast and coordinated, that after a few months of trying to fight back, humanity was quickly defeated.

These strange creatures are in fact, manomos: monsters that were changed by the last demon lord, who turned them from savage cratures to more docile and horny species.

They were once a peaceful race (most of them), who needed to breed with human males and consume their for food and magic. It seemed like a perfect love scene, but the catch was that they corrupted things around them, changing their surroundings and organisms into more manomo species. This of course, wasn’t tolerated by the chief godess, the deity responsible for all creation, and the Order, a society that fought against the monsters in order to prevent their corruption along the lands and were followers of the chief godess teachings.

Because of hatred against one another, many battles were fought in order to achieve dominance, until the final battle came to be. The Great Holy War happened, that occurred thousands of years ago, where the order and the demonic army made their stands to grasp the victory.

Years of battle and sacrifice led to the Order and the Chief godess’s sucess against the demon lord and her army. Outnumbered and defeated, the manomo’s population began reducing more and more as the order wanted to wipe them out of the face of the planet.

To prevent the extinction of the race, Druella managed to make a deal with the chief godess, where the godess spared the demon lord and her comrades if they would never corrupt any of her creations ever again. The promisse seemed impossible to Druella at the time, since manomo corrupted things around them involunatrily, but the godess found a way to solve that problem.

She cast the out the remaining manomo’s population and their husbands to the depths of the planet, underground land called Tartarus, that was located deep within the earth’s core. They were sealed there by the godêss herself, so that they could never escape again.

Over the course of history, Humanity prospered, but the Order started losing power and influence on society, since the people stopped believing in the existence of manomos, and the once powerful divine society was reduced to just a small secret organization that did not have as much power as their former past.

The chief godess also began losing power, since without the constant risk of the monsters, humanity had no more need for the godess and magic, advancing culturally and technologically as the time went by.

This lead to the extinction of magic on the surface of the planet, as humanity started becoming more dependent to the technology and to the money.

Inside Tartarus,however, things took a turn for the worse.

Because of small quantity of men avaible inside Tartarus, (whose’s mana was an important souce of food to most manomos) conflict inside the caves grew, while the demon lord wasn't able to solve the most crucial and concerning problem that affected their race: the incapability of the manomo to bear male children!

So in that way, the female population grew, while the male population remained the same .Due to the lack of new males and the impossiblity of getting new ones from the surface, manomo began starting huge harems in order to sustain themselves and inbredding became a commom thing down there,.

Men that stayed down in Tartarus were turned rapidly into male succubus, because of the initial corruption. But when they were exposed to more and more corruption along the years, they started suffering more transformations in their bodies, until they would also turn into manomo. To prevent that, the demons used their magic to prevent the transformation, and also began expanding the life span of the male succubus, so that they could satiesfy future manomo’s generations.

Due to their new surroundings and the lack of human mana, the manomo began slowly transforming into more primitive creatures, being guided by their instincts. They became more agressive and territorial against one another, fighting for the limited resources available.

Until they had enough.

They knew about the godês weakening and they took advantage of that, crating a plan to get out of underground prison and find more humans. They studied the human realm wit very much attention, coming with ways to strike them down and as fastly as possible. But due to the extinction of magic on the surface, they needed to return to Tartarus in order to recharge their magic abilities.

And now, 11 months after the incindent, most of the human population is inside Tartarus, enslaved by their new masters, while the rest of humanity struggles to survive in the new "earth", as they are hunted down like animals in this dark ages.
