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 Elemental Accords. A tournament that Earth has been chosen to take part in whether they want to or not. As a result, the entire planet is now a giant game. With people gaining access to skills and levels. For most, this is nothing short of a nightmare. For others, it is their chance to grab everything and claim the world as their own. Aurum Lockfeather has been chosen as a champion by one of the many gods taking part in the tournament. First, he just has to survive the week with monsters of all shapes and sizes popping out from every hole in the city.

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.

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.

I died and was accidentally reborn as an [angelic monstrosity]. So now I'm building a holy dungeon-tower that is tall enough to reach the gods...so that I can complain about it! But the humans think that I am trying to destroy the world.

The decision to start a new life is never an easy one, but for Joe the transition was far from figurative.

There is no weapon more powerful than the [Psychokinetic] mind. Astrid, a mischievous noble teen, long dreamed of exploring the ancient cities preserved beneath the waves, left behind from a time before the ocean swallowed the world.

But when an ancient monster long thought dead assaults humanity's last bastion–a floating ship-city–she awakens her System early.

When Alice Verianna went to sleep, she was just another teen from the Denver suburbs. She definitely didn't expect to be transported to a magical alternate dimension, inhabited by monsters and presided over by a mysterious System. Here, people resemble RPG characters and everyone has access to their own status screens. Grappling with the mechanics of the elusive System isn't the only challenge Alice faces. It seems an underground organization known as the Society of Starry Eyes has taken a particular interest in other dimensions.

Ten years ago, Amelia woke up alone and lost in a broken world where she had to fight for her survival. Now, after reaching the pinnacle of power, defeating the Void itself, and escaping the abyss, she has finally found her way back into the real world. But instead of returning to Earth, she arrives in the land of Vacuos. A fantasy world with magic, monsters, Classes, and Levels. A world that is governed by a System like it were a video game.

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.

Every year, the empire administers the rite of passage into adulthood. That rite serves to identify those blessed by Aether to become magi. The new magi are shipped to the academy to learn the arts of magic. The academy is a dangerous place; the tournaments held twice each year can cripple or kill the students, and the clans of the empire will go to great lengths to recruit the students they want. Gregory had one dream: to become a magi like the legends of old. Though he was ridiculed by the residents of the village and his unsupportive father, he never wavered from his dream.

After more than 700 years, he was expecting a peaceful and lonely end to his long life. That, however, was not meant to be. A single choice changed his fate, and his soul was forced to live again as a dungeon. Reborn but shackled to the heart of a mountain. This old soul has lost everything - and more. In a world of gods and demons, there is no room for a weak newborn dungeon. The path may be long and dangerous, but with a soul hardier than stone and a will stronger than iron, will he be able to forge his own destiny?

Now over a thousand years later, a certain sorcerer once again wakes...and he is not happy. Alessa has been on the run for years. Never stopping in one place for long.

After the death of his beloved mother, Swain is left at the mercy of his drunken father. His only respite from all the beatings and abuse lies in the words he scribbles down, seeking beauty in an ugly world through poetry. He has no friends until one day he meets a girl near his mother's grave. A restless spirit who calls herself Goose, over the years she encourages Swain's creativity, eventually helping him tap into a magical ability he never knew he possessed: a dark energy entwined with his despair, fueled by his anger, and controlled by his poetic verse.

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!

When Aesca Lampi wakes up in the form of her character from Eldest Fantasy Wars Online, she's annoyed by the historical inaccuracies. (Video-game-style scrolls? Really?) That is, until a building collapses on top of her, revealing she's on a fantastical island centered around the impossibly tall, glowing Tower of Aetherius . . . with an array of dangerous creatures—including jaguar hybrids, velociraptors, and giant, flesh-eating lizards—in the way. (Oh, joy.)

Liam was waiting for his father to come home from work when the house shook, and two moons appeared overhead. Stranded within a land where he doesn't speak the language and people are set on attacking him, he must survive in this new land where nothing makes sense.

When a new dungeon is born, it wants nothing more than to have the most vicious monsters, the most cunning traps and the most shiny of loot. There is only one problem...but it's a rather big one. It finished its first floor years ago, but it still hasn't been visited by any adventurers! In order to find someone—or something—to explore its floors, or perhaps just to find someone to talk to, this dungeon will have to go way off script. But it soon discovers that going off script brings problems of its own, and that adventurers are not the only thing this world is missing.

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.

On Ludus, life is often cheap. Nora's childhood hadn't given her many options. With nowhere else to go after losing her family, she joined an old friend in a street gang and found an unlikely home there. But unfortunately, tragedy is about to befall Nora. Grudges from the distant past and movements of shadowy organizations may take away everything she is familiar with and all that she holds dear...possibly even her life. Danger has never stopped her before, but survival may require escaping her old life and embarking on an insane, desperate journey.

Anya Nowicki, along with thousands of people around the globe, has found herself a host for alien technology known as the Archive. The Archive allows its hosts to alter their minds and bodies in an instant through holographic menu systems.

The gods should have agreed to fight the giants and let Ragnarök run its course and bring about the end of time. For a new world could only rise from the ashes of the old. But because the gods prophesied to die refused to take part, Yggdrasil - the World Tree - was forced to act before the stalemate led to the annihilation of the nine worlds and its very existence. And so I was born. One of the many seeds dispersed by the mighty World Tree, I was teleported through different planes and universes to find a new home where to settle.

Reborn into a fantastical RPG-system based world, Fresh is offered a second chance at life. Initially glad to have escaped her old existence, she quickly realizes that this new one might not be much better. Her new body is too frail to follow any grand dreams of adventure, her new mind is too dulled to allow any meticulous planning or thought, and this new, seemingly colorful, kind world is anything but.
