Dawn is coming:
Slannesh's laughter had echoed through the thousand worlds, an echo of lust and pleasure. But now, his palace, a masterpiece of delight and excess, was crumbling before his eyes. The walls, once gleaming with the colors of desire, now faded into gray shadows. The six rings of seduction that once shone with the fervor of submissive souls lay in ruins, and the gardens of his palace, which used to bloom with the beauty of the lost, lay withered and dry, his throne, his symbol of dominance was cracking.
Slannesh, weakened and hungry, clung to the remains of her existence. The demons that once danced around her now devoured each other, trapped in a cycle of despair and withdrawal. The Tide had flooded the galaxy, taking with it not only the souls of mortals, but also the champions who had been its own. Its wrath was concentrated on the horizon, where it could feel the presence of its torment, a force that had begun to dismantle the rules of the Great Game. The Tide came to flood the galaxy, upsetting the status quo, it did not come to play the great game, it came to end it, taking from them what was rightfully hers, it rescued Isha from the rotting clutches of Nurgle! This is not fair! Isha must be hers, it is her right over all the Eldar!
"Isha! Ynnead! Tide!" he screamed, his voice full of hate and agony. The Eldar goddess, the new god of death and the tide emerged as heralds of his doom. In her splendor, Isha was no longer the captive and abused goddess, nor was Isha even the benign eternal queen, instead, she was Isha the queen of the wild, a being who gathered the essence of the brutality and survival of the wild, while Ynnead, like a silver judge, emerged with the certainty of death without redemption, and the tide rising as a monument of life and righteousness, a punishment for all the sins of the galaxy.
The storm grew stronger, and Slannesh felt the weight of countless souls crushing her will. The Tide, a colossal entity, assimilated everything in its path, its essence composed of the souls that should have fed Slannesh. With each beat of her heart, the goddess of pleasure understood the truth: she was being stripped of her power, her influence, her life.
The tide with the voices of unmurderable souls gave its sentence that made the foundations of the warp tremble "Your foundations are crumbling, we are your punishment, I am a monument to ALL YOUR SINS AND YOU WILL FEEL THEIR WEIGHT, YOUR VOICE WILL BE SILENCED!"
Isha advanced with a spear of wood and thorns, her cold and merciless gaze fixed on Slannesh. "This is the end of your depravity, it is time for you to return all that you took" she whispered, her voice echoing like the roars of beasts in the vast darkness. Without warning, she pierced Slannesh's abdomen with the spear. A heartbreaking scream escaped her lips, not of ecstasy, but of unimaginable pain.
With one cruel move, Isha ripped open Slannesh's stomach, allowing a multitude of souls to flow freely. Sights of horror unfolded as the remains of Eldar gods, half-digested and dead, emerged from within. Isha gathered their essences, preparing to rebirth that which had been consumed.
Slannesh's agony intensified as she watched Isha raise her fallen loved ones, preparing to plant their metaphysical cores in her new garden. Desperation filled her, a never-ending need to fill the void that had opened up in her being. In a last attempt to maintain her existence, Slannesh pleaded. "Stop! You cannot do this... I am the goddess of desire! I am Slaanesh!"
But Ynnead, the cold judge of death, approached with her sword raised. Slannesh felt the icy terror she had never experienced. "No more, this is your end," Ynnead said coldly, and before she could finish her plea, the blade descended.
Darkness swallowed Slannesh. The void of true death enveloped her, and her realm, her domain of lust and pleasure, vanished with her final breath. Laughter and screams became distant echoes, there was a great emptiness in what used to be Slannesh's realm, the cultists who still worshipped her suddenly screamed in horror and pain as they felt the void that consumed Slannesh, and dread loomed over the other gods of chaos causing ripples in the warp.
The Great Game had changed forever. The Tide had claimed its place, bringing with it a new order of life and death. In this new world, depravity and desecration had been replaced by the salvation of what once was.
The dark gods for the first time in their existence felt fear. The long night was drawing to a close. Dawn was approaching, and the Tide had ushered in a new beginning, one where the echo of Slannesh's laughter would never again echo through the cosmos.
