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. Humanity will be left defenseless. Drew Wright knows none of this. At least not until he is rudely ripped from his bed and thrust into a white room to undergo a taser-happy ‘Tutorial’. Turns out, he is one of a thousand randomly selected people to be forewarned of the approaching apocalypse. Now, he faces the delightful task of convincing his wife and mother of the devastation hurtling towards them.

Silas is inducted into the System, becoming the last in a long line of Earth's "forerunners." The rewards are great, but the danger is greater. We are not alone in the universe. 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?

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?

With one touch of the stone, Tyron receives his Class and his life changes forever. In an instant his bright and promising future as the scion of two powerful Slayers is torn apart and he must make a decision.

As humanity is taking its final breath, facing extinction from a myriad of monsters, the last three people on earth are creating a final chance for the hero to go back in time and stop the apocalypse. 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?
