After narrowly surviving an invasion of her dungeon by some seriously dangerous Elves, Sandra needs to recover from having all of her defending constructs destroyed in the process. With the bulk of her forces lost while shattering the Core of a Reptile Classification dungeon, the merchant-turned-Dungeon Core is feeling a little vulnerable.   

A time of great darkness is approaching, but will Sandra and her dungeon survive? After being responsible for destroying multiple Dungeon Cores, the consequences of which she has yet to see but knows will be coming, Sandra and her friends must obtain help from the leadership of the nearby lands. The problem will soon become bigger than she can contain, and only by them all working together will everyone survive the dangers represented by the nearby dungeons.

As Robia Valley recovers from the necromancer attack, Regan and Louella work to increase their strength to meet the coming challenges. In the dark, forces move to unknown means. Adventurers come from far and wide to test their strength in the rumored dungeon. Join them as they make their journey. 

Artorian shrugged off moonfall and war like it was a gentle rain and must now face new trials. Specifically: life in the world created by the Dungeon Core, Cal. Unfortunately, Cal has only put together the most bare-bones of systems. He's no stranger to solving near impossible problems; how difficult could it be to smooth out the slew of angry Mages with bitter rivalries, uncountable hidden secrets, a complete inability to cultivate, and a Dungeon creating messes at full speed? One way or another, it is up to Artorian to pick up the pieces.

In search for the townspeople of Gatecross and his Core Power Guild, Fred and his friends wind up in the city of Allroads - where they find more than they bargained for. After successfully breaking them all out of prison using his special abilities and creating a small dungeon underneath the city, his activity unfortunately gained the attention of the elemental Dungeon Core factions surrounding the large valley where the city is located. 

Clyde Hatchett and the rest of the Skull & Thrones better play their cards right - otherwise their newly formed guild will fall in a war with the Iron Silents, the overpowered immortals fond of spawn-camping and, well, anything that puts them ahead. So much for resting on laurels, huh?

Old Man Vincent is heading for the top of the World-Tree and beyond in the final installment of the World-Tree Trilogy. To get there, he's going to have to overcome titan-sized bosses, strange new worlds, an army of angels, and a seemingly invincible final boss. And yes, he's looking forward to the challenge.

The horde dealt with, Regan turns his attention to the north. As he works to increase his children's and his power, events in the world seem to be against him. Powers continues to grow all around the continent in response to this new player emerging on the map. Louella only wants a few moments of peace to process the changes happening to her and her valley. No one wants to give her that peace as her valley grows to be the center of the continent. 

Regan Earle was a robotics scientist that inadvertently caused the robot takeover of the world. When his last creation completes a decade-long plan to end his own life, he ends up surprised. Creation offers him a second chance to test his wits and cunning in another world. Fate, however, is fickle and Regan ends up as a Dungeon Core...with all his memories. Is the world of Murgin ready to face such a dungeon? Let's find out.... 

Tired of the necromancer threat, Regan increases efforts to deal with them at their heart of power in the north. Seemingly aware of his presence, the monster horde continues to grow until finally they charge the valley. Steel Spire, one of Regan's sub-core ends up attracting their attention. Will his new inventions be able to handle the mass of monsters? Meanwhile, Louella has her own monster horde to deal with. Enlisting the aid of the adventurers that have come to her valley, she marshals a force to meet the horde on the battlefield. 

Enemies emerge everywhere. Stagnation starts seeming standard. Results require Ruthlessness. Joe has been moving deeper into his study of ritual magic and further away from his combat team. He's learning more and more, but more often than not needs to choose between his research and squad leadership. Improving the town is a huge help to the guild, and they have been pushing to increase their power. Their rapid increases have not gone unnoticed. The guild receives an ultimatum, delivered by assassins and signed with blood.

An end of the world. The start of a new one. A thousand places to be. Artorian has survived his encounter at the Ziggurat, but at a sharp cost. However, the powers in the world are moving and there is no time to rest. Even if Artorian doesn’t realize his part in it, the next stage of the great plan is set in motion. In a place of mountains and dales, the old scholar must seek new information in order to puzzle out the last pieces and gather victory with his own two hands.

After his town is put to the sword and the children are taken to replace the fallen, an old man is out for revenge. He’s ready to fail at the most difficult challenge in the world: cultivation. Too corrupted to even take the first steps, the sly old elder simply agreed with those who told him that it was impossible. Then, he quietly ignored them, rubbed his hands together, and started anyway. He had always failed in what he did. The only thing that had never failed him was his sharp mind and philosophy. He would cultivate...no matter what it cost him.

The path to the top is never easy...The title of Serpent King is up for grabs, and Torga's going to need the power it brings to protect his new family. Standing in his way are eight Royal Serpents and a host of shadowy forces who want to manipulate Torga for their own personal gain. As if that wasn't enough, the jotnar are returning to Asgard, threatening the people Torga swore to protect. He has to become stronger, but will his allies pay the price for his rise to power?

With the help of an unlikely ally, Fred has secretly obtained access to all seven elements for his Core without the Supreme Council of Dungeon Cores’ knowledge; Fire, Water, Nature, Earth, Dark, Light, and Air are now technically at his disposal. However, despite having access to them all, he finds himself behind enemy lines without the use of any but Light and Air due to his temporary Core he had created back in his dungeon.
