When the Order makes a catastrophic mistake, transforming Alexandra into a dungeon core, they inadvertently give her the power to bring back technology long since thought lost in this world.

Hannah has a routine. Wake up, take a shower, go to school, go to work, come home, and pass out. It's a perfectly normal routine for a perfectly normal girl who does not have to remember how her limbs work every morning because of haunting nightmares of being a very different creature in a very different world. That's all she thinks they are—nightmares—until one night, they're all too lucid, and her body on Earth starts to change. Slowly, Hannah's humanity starts to slip away... but surely she can continue just sticking to the routine, right? It'll be fine. It has to be.

Growing up, she was the girl down the street. Even then, I knew she was different. She was tough, rough, and had the strength to stop a speeding car with her bare hands. We were as thick as thieves, sharing every adventure. Then one day she revealed a secret. She wasn't from Earth. She was from a distant place called the Arcadia Multiverse. Her people lived under the rule of a god-like entity known as the System. That System had its gaze fixed on Earth. And it was only a matter of time before it came for us.

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.

The Netherworld: it is a hellish landscape inhabited only by demons. Joining the ranks of newborn demons, Salvos is thrown into the violent, anarchy-ruled landscape of that world. To survive, she will have to learn, she will have to adapt, and she will have to evolve. She will gain experience to reach new Levels of power. Her curiosity aids her but her pride could be her fall. It is the nature of the Netherworld to avoid or conquer any threats faced. After all, the law of evolution is survival of the fittest, and Salvos is a survivor.

Zaria was just a normal woman, living a simple life—until demons burst through her door and ate her heart. Reborn from tragedy, Zaria rises from the ashes as a Core, but with a twist. A rare mutation has turned her into a Mutant Core, destined to explode unless she forms a bond with a human witch to become a Striga. Her mutation? Legs.

Along the way, she battles demons, builds her dungeon, and feeds her mimic mobs.

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.

His family has been cursed by a broken class for the last fifty years. No one has ever managed to level it, condemning them to the lowest paying jobs and life in a barren village.

When Kers is reborn as a dungeon core, he finds himself stuck in the most improbable of places: a cloud. High in the sky and far away from the usual solid resources, Kers must face the obvious question: How is a dungeon to build itself without wood or stone? Luckily, Kers has the sarcastic (and sometimes helpful) fairy Selena to help him get his bearings. Together, the pair delight in exploring Kers’ weird existence, creating novel mobs, and enticing adventures to plumb the lofty heights of his floors.

It's not easy being the most famous and attractive villain in the United States, but somebody has to do it. And it might as well be Via Rodriguez, aka "Empress." Via's used to outsmarting the ever-so-arrogant Heroes that come her way. Her wicked schemes take an unexpected turn, however, after a getaway gone wrong lands both her and her current foe—the annoyingly perky Electra—in the middle of an unknown land that is definitely not Earth.

Nature is dying. Perhaps before the world is turned into an industrious machine, nature itself can play one final trump card to save itself. Summoned to a new world, a mushroom-loving mycologist needs to grow up and grow stronger in order to accomplish the goal that brought them to this new place: to save nature from the system that the sentient races have created. Stats, levels, classes, and skills are all well and good, but when you're a Child of Poverty in the slums of City Nineteen, there's little you can do to change the world. Not unless you're willing to think outside the box!
