Imagine a life where you have a home, a loving family, and loyal friends; where the days flow smoothly and brightly. This was the existence of twenty-two-year-old William Farrow from Pennsylvania. He was studying at university, dreaming of earning his diploma, finding a job that would provide a decent income, and continuing to live a simple, peaceful life.But then, one day, everything changed. Whether it was fate or a series of quiet coincidences—who can say? A trivial delay became the first domino in a chain reaction that thrust William into a world of mysteries, a string of murders, and dark supernatural phenomena. Since then, he has felt like a pawn in someone else's game, caught in a struggle against forces so powerful that he still struggles to find the words to describe them.And it gets even more intriguing. He discovered that the world is not as it seems. Do you believe in Bigfoot? William would have laughed too… until he encountered one in real life. Vampires? Ghosts? Demons? Name the creature—and William would simply shrug: “Yesterday, that thing tried to eat my neighbor.” As if that weren't enough, a heavier surprise awaited him: it seems he is not entirely human. Something foreign stirs beneath his skin, awakening in the dark, and the world responds to it with an unfamiliar echo.Now, all that remains is to learn the new rules and figure out how to navigate the world he has unexpectedly become a part of.

Within this darkness full of despair,
A single person escaped from space-time, returned to before the world collapsed, determined to change the fate of the past.

But as time pass, he gradually finds out that the Apocalypse isn’t quite as simple as he thinks…
