The World After The End offers a fresh and gripping take on the post-apocalyptic and regression genres. Written by Sing-Shong, the author of Omniscient Reader’s Viewpoint, the story explores the emotional and psychological weight of being left behind.
In a world where humans were forced to become “Walkers” and clear a mysterious tower to save humanity, the discovery of the “Stone of Regression” on the 77th floor changed everything. The stone allowed Walkers to regress to the past, giving them a second chance to correct their mistakes and alter their fates. One by one, Walkers abandoned the current timeline, leaving behind only a handful of individuals who refused to give up on the present.
The story follows the last remaining Walker, who reaches the 100th floor alone. Faced with unimaginable challenges and the looming threat of complete annihilation, he is forced to rely on his strength, intelligence, and determination to survive. The tension between hope and despair, along with the protagonist’s inner conflict about whether to abandon the world or fight for it, creates a compelling and emotionally charged narrative.
The detailed world-building and the exploration of the protagonist’s psyche make The World After The End stand out. The concept of regression as both a blessing and a curse adds depth to the story’s themes of sacrifice, loyalty, and survival.
Plot of The World After The End

The story takes place in a dystopian world where humanity’s survival hinges on clearing a massive tower filled with deadly monsters and hidden secrets. When humans were suddenly summoned as “Walkers,” they were tasked with ascending the tower to prevent the collapse of their world.
The discovery of the “Stone of Regression” on the 77th floor allowed Walkers to return to the past, effectively giving them a chance to correct their mistakes and strengthen themselves. However, this also led to most Walkers abandoning the current timeline, leaving behind only a small group known as “Carpe Diem,” who chose to fight for the present rather than reset the past.
The protagonist, the last remaining Walker, ascends the tower alone after his comrades either die or regress. He reaches the 100th floor, where he is confronted with the truth behind the tower, the meaning of regression, and the fate of humanity. As the final Walker, he faces impossible odds and must decide whether to embrace the power of regression or forge a new future without turning back.
The protagonist’s resilience and moral struggle drive the story forward, as he uncovers hidden conspiracies and faces enemies both inside and outside the tower. His determination to protect what remains of humanity and his refusal to regress make him a unique and compelling figure in the story’s dark and unforgiving world.
