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.

Zac was alone in the middle of the forest when the world changed... The whole planet was introduced to the multiverse by an unfeeling System... or God. A universe where an endless number of races and civilizations fought for power and dominion. Zac finds himself stuck in the wilderness surrounded by deadly beasts, demons, and worse. Alone, lost and without answers, he must find the means to survive and get stronger in this new cut-throat reality.

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.

When Kers is reborn as a dungeon core, he finds himself stuck in the most improbable of places: a cloud.

Together, the pair delight in exploring Kers’ weird existence, creating novel mobs, and enticing adventures to plumb the lofty heights of his floors.

Either through plan or chance, he’s alive again, and planning to enjoy himself to his heart's content.

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.

Pete is a simple man who enjoys a good drink amongst good friends. Not too much to ask, right? Now, he's trapped in a fantasy world far from home, stuck underground and inside the body of a smelly dwarf with fantastic facial hair. The worst part? The swill that the dwarves are falling all over themselves to drink. It's flat, it's watery, and it has the alcohol content of a rancid coconut.

Will is the newest in a long line of dungeons born into the world — and he’s a rank higher than any dungeon that preceded.

Ryker only has one goal in his life right now: Turn a certain adventuring guild into a flaming wreck while dancing merrily through the smoldering ruins. All for the chance to get back at a handful of people. It isn’t as if they didn’t deserve it either. They had driven him from his home. Chased him physically from the very guild house itself. Simply because he wasn’t as strong as they expected him to be. As strong as he’d expected himself to be. He’d returned the next day and left with something he’d hidden away and told no one about when he found it in one of his few Dungeon Dives.
