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.

Ryan doesn’t remember much about his life before becoming dungeon core. Only that he had a bit of a disagreement with the church - something to do with a beheading? Now reborn, Ryan begins to arm his darkness dungeon with devious traps, bestial zombies, and ill-named skeletal creations, without doing anything too evil. Well, mostly. Some adventurers just deserve a stalactite to the head. But Ryan quickly learns being a darkness dungeon isn’t all loot and bone puns.

Death came on swift wings. A soul, blessed by a goddess, falls to the land and enters his new life. He clings to a single memory, the defining moment of his previous life. Now he learns how to succeed in his new life as a new dungeon heart. To become the best dungeon he can be, he partners with the one existence all dungeons need: his bonded dungeon pixie.

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

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.

Throughout the Kingdom, Defenders constantly fight against incursions of dungeon monsters rampaging over the border the Kingdom shares with the Wildlands. To keep the danger to their citizens low, they periodically sweep through these untamed areas filled with natural beasts and roaming dungeon monsters, destroying as many Dungeon Cores as they can find. Tempara was practically a newborn when Defenders from the Kingdom snatched her away, only to be forced to watch in horror as tragedy fell upon the rest of her pack. 

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.

Daxas has established his dungeon in the Proving Grounds and incorporated two more into his sphere of influence. But his expansion and rule-breaking doesn't end there. His successes have been impressive, but thus far, he has been competing against the other minnows in the Proving Grounds. Other, grander forces, have taken notice and the interfering Divine Lords continue in their campaign to see Daxas destroyed. Daxas will have to think bigger, fighter harder, and cheat in ever more inventive ways if he and his growing pool of desirable disciples are to emerge victorious.

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 decades, the governments of our world have been fighting a desperate and secret battle to keep hordes of alien invaders away from our planet. When the guardian of the United States falls, a new champion must be chosen. Sadly, the choice of a champion isn’t ours to make, and the Galactic Conflict Authority selects a human, seemingly at random, to lead the United States of America’s efforts at holding back the tide.

The decision to start a new life is never an easy one, but for Joe the transition was far from figurative. Becoming a permanent addition to a game world, it doesn't take long to learn that people with his abilities are actively hunted. In fact, if the wrong people gained knowledge of what he was capable of, assassins would appear in droves.  

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. 

Elmer Robbins loved decorating for every holiday with his wife, Mary, by going all out with décor at their cozy little house as well as filling his office with holiday cheer. But when his beloved Mary passed away unexpectedly the year before, it was difficult for Elmer to summon the same sort of enthusiasm in decorating for all of the holidays without her beside him.

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....

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.
