Lucas was shocked when he awoke to find the world had ended. An alien AI called the System had taken over Earth and transformed his apartment building into a 100-floor dungeon tower of traps, monsters, and loot. Trapped at the top, Lucas and the other residents have just one year to reach the ground floor and escape before the tower self-destructs. That’s his first problem. The second is he slept through the System’s welcome orientation, so a Class was picked for him. Lucas is now a Blood Reaver. A brutal Class based on speed, ferocity, and striking from the shadows.

Quest Academy stands defiantly against them as a place to train the next generation of Heroes. The Guild Association is holding the line but is in dire need of new blood and the powerful abilities they could bring to the battlefront. To be the saviors that humanity needs, they need to surpass the limits of those that came before 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?

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.

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.

None of this mattered much to Derek, aside from making living a little more perilous.

Five years in the prime of his life, wasted. And now finally, after so long, he was returning to society, ready to resume his life. And this time he wouldn't make the same mistakes. This time, he would do it right. Yet just as he was about to gain his freedom...everything changed. He found himself in a new world without explanation, a world of magic and possibilities beyond his wildest dreams. Orc, elf, ogre…hundreds of possible races. Blacksmith, fighter, rogue…thousands of possible classes. And each of them with tens of thousands of possible skills.

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.

Moments before his untimely demise, Felix was snatched from earth and thrust into a magical world known only as "The Continent".
