Dabu’s life has been far from easy; born with a crippling lung illness, he has never been as strong as his father or brother, both of whom have disappeared after attempting to challenge the Trials of Ancients. In the wake of the Tyrant King’s war, his village has come under the control of the Purus, a vicious gang of magically enhanced cutthroats and murderers. The Trials offer the promise of power to any who can clear them, but Dabu has been forbidden from entering.

Portals appeared on Earth, forcing everyone to make a choice: Enter or die. However, if they managed to survive through all twelve planets in the system, they would be allowed to return home. Humanity fought bitterly and, in the end, succeeded, but the cost was high.

Multiverse Z came knocking, snatching all the humans from Earth to integrate with their game-like realms of magic. No warning. No tutorial. It's an instant transition where eighteen-year-old Joey Eclipse is thrust from his relaxing night playing video games to a stone room with two doors. There's nobody but him. The system messages asking some cryptic questions: [Adventurer or Commoner?] [Greatness or Steadiness?] And more. Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

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.

After his parents died, Alex Roth had one desire: become a wizard. Through hard work, he was accepted into the University of Generasi, the world’s greatest academy of wizardry.... Fate, however, had another plan. On his 18th birthday, he is Marked by prophecy as one of his kingdom’s five Heroes, chosen to fight the Ravener, his land’s great enemy. But his brand is "The Fool". Worst of the marks.

It was a day like any other when suddenly the world changed. The universe reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A place where power is the only thing anyone can truly rely on.

Jack Rust was a disillusioned biologist with a PhD—almost. When an extraterrestrial AI calling itself the System invaded Earth and thrusts it into a world of aliens and violence, the least Jack hoped for was gaining access to magic.

It’s not easy making the career jump from office-supplies-store middle manager to heroic interdimensional adventurer. At least, Jason tries to be heroic, but it's hard to be good when all your powers are evil. He’ll face off against cannibals, cultists, wizards, monsters...and that’s just on the first day. He’s going to need courage, he’s going to need wit, and he’s going to need some magic powers of his own. But first, he’s going to need pants.

Reidon Ward will become a god. He doesn't know it yet, of course. Reidon was born weak, sickly, and small. Afflicted with a painful disease and abandoned by his parents because of it, he has had to fight tooth and nail for every minor advantage life has allowed him. However, his perseverance has not gone unnoticed, and when the most powerful artificial intelligence in human history takes an interest in him, things began to change quickly.
