Multiple Timelines Theory

Multiple Protagonists are being Isekaid into a world that is....a secret!

Across timelines A, B, C, and D, reality fractures. Humanity collapses. And one broken soul begins to remember it all. But when you realize you were never born… only made… who do you become? "They called it a survival game. They didn’t tell us we were experiments. They called it an apocalypse. They didn’t mention it was my fault. Now timelines are collapsing. The gods are watching. And I’m the only one who remembers everything. Even if it kills me, I’ll break the loop. Because she’s still in there. Waiting for me to find her."

I died with her voice in my code—and woke up with nothing. No power. No past. No name worth keeping. Just a child’s body in a world where men obey, and women command breath, blood, and flame. The House of Anara runs the monastery that reshaped me. They think I’m quiet. Useful. Harmless. But I’ve begun to see the gaps in their structure. I have an eye for patterns. A mind built for systems. And more than anything— I have memory. I have theory.

"Alright, here's a task to clear out a goblin nest, you..." "Charge!" ------------------- Elements: [Bottomside Adventurer], [Hodgepodge World View], [Pseudo DND]

Aeden no recuerda cuándo empezó a sentirse fuera de lugar. Solo sabe que no debería estar vivo... En un mundo que le resulta familiar y ajeno al mismo tiempo, voces que no comprende, recuerdos que no le pertenecen y personas que desaparecen lo arrastran hacia una verdad que no está listo para aceptar. Cada muerte reescribe la línea del tiempo, cada encuentro revela una grieta en su existencia. No hay nombre. No hay origen. Solo una pregunta: ¿Qué se rompe primero: la realidad o uno mismo?

Stephen Hawking, He was regularly asked for his thoughts on the “big questions” of the day by scientists, tech entrepreneurs, senior business figures, political leaders and the general public. Stephen maintained an enormous personal archive of his responses, which took the form of speeches, interviews and essays.

He had lost some of his physical abilities due to any spinal issue ... But, in his mind, he was completely free, free to travel around anywhere, free to explore the existence itself ...

Warning From Earth A dystopian work of fiction written by Rey, depicting a world in global chaos due to secret projects unmonitored by the public. Although it contains real elements such as geopolitical conflicts, country names, and world sentiments, the entire story is purely fictional. Every character, organization, and event depicted is the result of imagination, arranged to illustrate an alternative theory about hidden forces that control the direction of the world.

(Vol. 1 completed. Vol. 2 in continuation...) Short Synopsis: A politician from Earth gets transmigrated into a semi-familiar cultivation world, where typical Xianxia protagonists are cooking trouble in every corner of the street! Guided by a unique system, he begins to amass a legion of such children of destiny, manipulating each of them into becoming his fan and a partner-in-crime. What to expect: 1. Extremely overpowered enemies who actually have a brain. 2. Side Characters who make impact on the story 3. MC schemes more than he fights, and he ALWAYS fights dirty. 4. There are tons of scheming by side characters that even the MC can't easily deconstruct. 5. MC's cultivation method is fucked up beyond anything you've read on Webnovel. It grows wilder with each arc. So don't expect typical power-ups and revenge subplots. 6. Dry, lowbrow comedy is common across all of my writings. I know it's not everyone's cup of tea, but I can't help it.

This is not a linear story. Fractura: Rise of the Rift is a fully planned epic that unfolds across multiple timelines, worlds, and perspectives. What begins as a portal opening and a sudden attack soon reveals itself as part of an ancient conflict between light and darkness — with characters whose destinies are deeply interwoven. The narrative shifts intentionally between past and present, memory and choice, loss and awakening. Each shift adds a new puzzle piece — and with it, new understanding. Readers can expect a story rich in depth, with intricate world-building, real conflict, personal growth, and many moments where what you thought you knew is suddenly redefined. If you're looking for a story that challenges you, moves you, and constantly surprises you — this is your invitation to enter Fractura.

Twelve Thrones is a tale of twelve kingdoms, each with its own perspective, allowing you to follow one, multiple, or all as you decide who you want to see triumph in the end. But remember—this is a story of war, power, and ambition, and not all kingdoms will survive to the end. Twelve Thrones: United Islands of Khiz (UIK) Perspective tells the story of UIK, a collection of islands bound by the sea and a complex network of political and familial ties. The people of UIK are defined by their resilience and resourcefulness, as they face constant challenges both from the seas and the political ambitions of other kingdoms. As the ruling class of UIK navigates shifting alliances and internal power struggles, they must also protect their homeland from those who seek to control the valuable trade routes and resources of the islands. The first 25 chapters will cover UIK's history, uploaded weekly on Mondays at noon. Afterward, the main story begins with shorter chapters (1–2 per week) focusing on the present day. Unlike the history chapters, the story won’t have dates and will follow one character—you’ll need to piece together the timeline through character interactions and events. I recommend reading the series in date order to fully grasp the unfolding history. If the story gains popularity, I might include a date order map on each perspective.

So yeah beyond our skies are the nine planets. That's what scientists would have us believe. The multiverse theory should only be discussed within the confines of some fantasy novel. But what if you had the chance; the fortune(or misfortune) to be coerced into multiversal journeys. The painful kind. What would you give to experience worlds beyond your own.

(Does a perfect being have the right to understand someone who is not? Would he be able to understand his suffering? his sorrows, his pains? why, why would a perfect being have the right to decide on someone who is not perfect by believing he can understand him!!)

What is love? Some people believe it's the best thing to ever happen to you, while others believe it's the worst. Regardless of which of those two theories are more accurate, the truth is love is real, and we all feel it at some point. It may be platonic, romantic, familial, religious or self-love, but at some point, we feel it. How we describe that love is completely up to us. This is just another love story.
