Thousands of Heroes protect the land, defending against the periodic incursions by gigantic monsters known as World Threats. This was the way it had always been and Clay Shuntwise was perfectly fine with that. Running deliveries for his family’s shop in the sleepy town of Renton, the young teenager barely even thought about Heroes and their role in keeping the world safe. That was, at least, until a World Threat came crashing down on him.

All that Tacca GloomLily ever wanted to be since she was very little was a fairy assistant to a Dungeon Core. After her negatively portentous birth, however, she was never fully accepted by her superstitious peers and instructors at the Dungeon Assistant Preparatory School. Nevertheless, she persisted in her studies and graduated at the top of her class. Unfortunately for her, the “hands-on” training she was supposed to receive from a mentor and his bonded Dungeon Core didn’t go the way she would’ve hoped.

James thought he would be just another adventurer in the world’s most anticipated dungeon delving VRMMORPG. But when he logs in, he soon finds out that he won’t be diving the dungeon - he will be creating it. Pretty awesome right? At least that was what he thought when he boldly chose "Random" as his dungeon type....

Newborn Dungeon Cores must choose what entity they help contain, and that choice determines what monsters they are able to summon. After being executed for crimes forgotten in death, Tira is given the chance to make that choice. Tira chose Acekorah, the Primeval Terror, a being so dangerous few cores will risk trying to contain it. 

David always was an outdoorsman and an explorer. But when Earth merged with the magical world of Tannoris, it suddenly became too dangerous for anyone without a Class to leave the cities.

A mystical ritual will awaken his Class, and a budding homestead on the wild frontier is waiting for him to take ownership.

The Demon Lord is dead. The System is broken. Somehow, Elias Hearthsong is neither of these things, despite being at the final battle of the Demon Wars. He is a Master Enchanter, perhaps the last one alive. Determined to keep a promise, he crosses the continent to protect his dead friend's legacy: a crumbling orphanage run by a beautiful kitsune. He isn't a teacher, nor does he have experience with children. But with the love of a few good women, anything can become possible.

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.

But Matt can be a great tool against the evil forces. TreeTree (as Matt comes to be known) will learn all sorts of skills, gain levels, and in doing so, build up a forest, train young subordinates, protect a village, and more.

Milton Frederick was originally abducted from his apartment to help defend one batch of pacifistic aliens called The Collective against another set of homicidal aliens called Heliothropes...but he never quite made it that far. Instead, during the process where his human consciousness was ripped from his body and inserted into a massive metal contraption called a Station Core, the ship that he was being transported on blew up and he was sent hurtling through space.  

Marstin Hardgrove was orphaned at a young age, forced to live on the streets, and needed to turn to thievery to survive. When a job goes wrong and the young man was caught, he was forced to eat a handful of dirt and rocks before being abandoned to die; unbeknownst to Marstin, he also ended up swallowing a tiny dungeon crystal.

Lich is the newest Dungeon Core to grace the world. But he doesn’t conform to the usual four energy types—nor Air, nor Earth, nor Fire, nor Water. Instead, he is a Soul Core. Glimpses of his previous life haunt his dreams but offer clues to solving the mystery of his bizarre magical affinity. Memories of an undead city, burning light, and an order of terrible crusaders fill his thoughts.

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.

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?

For Daniel, a zombie apocalypse couldn’t have happened at a worse time. If he’d been back at the farm, he might have stood a better chance than most. Instead, Daniel woke up in a distant hotel room armed with nothing but a hangover.
