Myst, Might, Mayhem - Chapter 23

Stumbling upon a game, I found myself immersed in a script brimming with excitement: superpowers, oddities, curious artifacts, and demons...Here, one can not only delight in the pleasure of grinding but also touch an infinite degree of freedom and even experience the curious thrill of being carried away by monsters!Let’s not talk too much, happiness, just happiness is all that matters!

Joseph Knox, one of the most prolific and well-known serial killers on the planet.A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world
