Then a message appeared in his vision: [60,000-year countdown has ended] [Nemesis 1 released] [Please acknowledge].

An AI calling itself Schema has assimilated Earth into its System. As a consequence, everyone gained access to status screens, power-ups, and skills. This AI turned these concepts from fiction to fact. It's easy to become intoxicated with leveling up and becoming stronger. To some, it's too good to be true, like living out a dream.

In just seven days, the world will crumble. The System's Descent will usher in a new era of chaos: wild animals mutating, monstrous creatures emerging, and the cessation of modern technology.

Zach grew in power and thrived in the post-Framework world. He became a respected leader, a shining example of what it meant to be good.

Yet not even with his incredible power was he able to stand against the World Ender. His arrival in the new realty, the Infinite Realm, gives him the chance to grow stronger, to find the monster again-and make it pay.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.
