As reality's grand show concludes and alien watchers abandon and reset Earth, the world dissolves into primeval chaos. Monsters roam, magic surges, and the survivors battle to reclaim their world. Humans are forced to adapt… or become extinct. But humans aren't the only players in the game. Cunning mandrills now weaponize Earth's creatures, laying waste to the remnants of humanity. Warring dinosaurs, primordial monsters, and alien beasts complete this apocalyptic free-for-all, each hungry for their next kill.

The 42nd Merging arrives, mass-transporting every human to a hostile new world with a System. Everyone must choose a Class, and Quest directives compel them to climb the leaderboards for categories like highest level… and most kills of other people. Jordan isn’t anyone special before the Merging, but the new start equalizes the playing field. He must exploit his versatile class to overcome powerful monsters and opportunistic strangers who kill people as a quick path to power.

Orodan was an orphaned street rat who clawed his way to the county militia with hard work. When calamitous events unfold and draw him into events bigger than himself, Orodan's battle-loving disposition leads to a warrior's death. Then he wakes up again at the start of the Cataclysm. Then again. And again. In a world of skills, titles, and blessings, a smart time-looper would perhaps scheme, plan, amass equipment, and allies. But not Orodan. If there's one thing he's good at, it's stubbornly trying the same thing over and over again via brute force till it's done.

Benny White had been having a rough couple of years, and the approaching apocalypse wasn’t exactly helping. Pulled from the point of death and thrust into a horde-mode-style survival game, Benny’s odds weren’t looking too great. To make matters worse, an eldritch god… entity… thing named ‘Dave’ tasked him with destroying the very System that now controls his fate. But hey, it's not all bad news. Benny’s experience as a lab tech grants him a rare Splicer Class that lets him repurpose the genetic material of slain enemies into augments for himself.

In the world of Alterra, forged from the ruins of Ragnarök and a nearly forgotten Earth, magic is everywhere. Despite this, half-elf Kiru and his mother live a quiet existence in a remote village where nothing ever happens. Nothing, that is, until the day Kiru gets into a fight with a rich lordling who breaks his spine.

Miles “Shrug” Lindstrom received a quest years ago. He was the only person who could see the window, and in addition to the quest, he could also see a countdown to the end of the world. Part of him was hoping that he was just insane and had been hallucinating when he first started seeing the window. Then again, if the quest was just his imagination, he was going to be massively in debt with a rental full of useless junk. But when the countdown finally stops, what happens is nothing like he could have imagined.

April 3rd, 3:46 AM. Planet Earth merges with the magical world of Arcadia, and a system gives humanity a choice: 40 years of indentured servitude, or entering a tutorial as a user to fight against the chaos incursion. Will doesn't hesitate—but the system thanks him for stepping into the fight by throwing him into an impossible tutorial. With little chance of survival, Will has a simple response: “Screw it. Might as well fight fire with fire."

However, before the hero can enter the chronomancer portal to the past, she and the portal's creator are both killed, leaving only the weak assistant to carry on their dream of saving the world. Will Nick be able to right the wrongs done to him, and prepare the hero for the world to come?

Alistair’s life is turned upside down when he is abruptly separated from his friends and family. As the universe slowly transforms and new laws take hold, everyone within his universe is cast into the trial—a crucible of survival and transformation. Before being set on his path, Alistair encounters a system avatar—a brief and enigmatic guide who offers little explanation, guidance, or aid before sending him and the rest of his universe into the unknown.

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

Freddy Stern, a twenty-one-year-old cashier, has lived a plain, albeit harsh life. Having been orphaned—twice—he's spent the last ten years working and staying out of trouble. His only aspiration is to save enough money to become an archhuman. His dream gets the jump on him when he barely survives a near-death encounter and finds himself in possession of 1% Lifesteal, a bizarre talent with numerous contradictions and just as many uses.

The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?
