Ryan doesn’t remember much about his life before becoming a 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.

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?

Matt is reincarnated as a Tree. Not just any tree, but an overpowered one in a fantasy world that serves as the battlefield for an ongoing conflict between demons and the heroes summoned to oppose them. 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.

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....

With one touch of the stone, Tyron receives his Class and his life changes forever. In an instant his bright and promising future as the scion of two powerful Slayers is torn apart and he must make a decision.

A world on the precipice of the apocalypse. A secret forged in the flames of war. A chance to start over. For John Sutton, only one of those three things matters. Retired from a decade of brutal war, he wants nothing more than a quiet pastoral life while he does his best to stem the steady increase of his Doom Points before they hit 100, signaling the start of the end. He’s been given a small farm on the outskirts of the empire as thanks for his service, but no matter how far he travels, it's impossible to escape the war's devastating effects on the world.

In the distant past, a time of magic and swordplay, there lived Harold, the mightiest lich of all, a master of arcane sciences, and a challenger of gods. After reaching the pinnacle of his power and finding it surprisingly bland, Harold waged a cataclysmic war against the gods, aiming to shatter the very system that confined him.

After fulfilling the duty all Arch Necromancers are tasked with, the last thing Sylver Sezari expected was to be reborn. He was usually the one reanimating dead things, after all. How ironic. But reborn he was. And after crawling his way back into the land of the living, he finds himself in a strange land, a strange time, and with a strange floating screen in front of his new face. Either through plan or chance, he’s alive again, and planning to enjoy himself to his heart's content.

Conquering dungeons and using them to grow has long been the most efficient way to become a powerful adventurer. The only thing keeping the process from being easy is the Beasts that inhabit these places. Questions plague those entering this particular place of power: Where do the ‘rewards’ of weapons, armor, and heavy gold coins come from? Why is a fluffy bunny charging at me? For abyss-sake, why are there so many monsters? Cal has all of the answers to these age-old questions for a very simple reason. He is a Dungeon Core, a soul forced against his will into a magical stone.
