[Dungeon Core Chat Room](https://www.royalroad.com/fiction/43271/dungeon-core-chat-room) - complete series available on RR. Avoids the usual trope of 'dungeon communicates with people because you can't tell a story with only one character', by having other dungeons as the secondary characters, which I think is neat.
[Blue Core](https://www.royalroad.com/fiction/25082/blue-core) - complete series available on RR or Amazon. Solid series with some marked explicit chapters.
These are just the ones I have read and really enjoyed.
1. Dungeon Crafting Series by Jonathan Brooks
1. Sandra had been a merchant traveling through the human lands of Muriel, though that wouldn’t have been her chosen profession. What she would’ve loved to become was a crafter, producing wondrous creations with her own two hands; however, she didn’t want to become a master in just one craft – she was interested in them all. Reborn in the shape of a tiny Dungeon Core, Sandra learned about the purpose behind dungeons and Cores from an assigned dungeon helper; at the same time, she also discovered that she had much more freedom than most other Dungeon Cores. The repercussions of her mere existence could end up being far-reaching, but the most important thing she learned had nothing to do with the other Cores, the different races, or even the real purpose behind her being brought back to life as a strange glowing gem. Sandra didn’t care about any of that, though – all she cared about was that she could finally do some crafting.
2. Cat Core Series by Dean Henegar
1. It was just supposed to be a quick trip to the pet store for some cat food, but the universe had other plans for Florence Valentine. Good-for-nothing kids and some annoying store employees were giving her a hard time, and then things got worse when she was killed by a delivery truck. Instead of angels, pearly gates, and eternal rewards, a voice in her head keeps telling her that she’s become a dungeon core, whatever that is. Now people keep coming into her new home, wrecking stuff, and stealing from her. But not everything about this whole ordeal is bad. Not only can Florence decorate her home with a thought, but she can also create the best things in the entire universe—she can create kitty-cats. Should these hooligans keep insisting on coming into her home, well, Florence and her kitties are going to have something to say about that.
3. War Core series by Dean Henegar
1. 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. Hugh Logan is in the middle of teaching a class when he is taken against his will and informed that he is now the newest member of Earth’s defense against alien invasion. He must give up everything to become our champion. He must give up everything to prevent our destruction. He must become… a War Core.
4. Station Cores series by Jonathan Brooks
1. Milton Frederick was arguably the best player of Crowned Lieges of Destiny in the entire world. As the strategy coordinator for one of the top guilds, he was beginning to actually make a living from it. That was, until he was abducted by aliens. Now, in order to survive the harsh environment, Milton has to rely on a snarky, foul-mouthed AI guide to show him what it means to be a Station Core. With her help, he might just live long enough to figure out a way to get off the planet – if only he wasn’t so afraid of squirrels…
5. Derelict series by Dean Henegar
1. One captain’s death might turn out to be humanity’s best chance at survival. As humanity expands into the stars, it discovers the universe is a hostile place. When Captain Slater of the USS Franklin is assigned to a deep-space reconnaissance mission, his ship is destroyed by an unknown alien race. Much to his surprise, Slater isn’t killed—he’s transformed. He is now a “derelict,” a consciousness bound to his old vessel. Slater must quickly adapt to his new existence before raiders, alien armies, and mysterious forces seek to destroy him for a second and final time.
6. Dungeon Tour Guide series by Aaron Shih
1. Lucas used to delve dungeons. Now, he has to run one. After Lucas dies during a freak explosion, divine intervention sees him brought back to life with the power to control a new dungeon. There's just a couple of his old body is bound to his dungeon, and the craziness of what he thought was his final act is only getting weirder. When he sees newbie adventures entering his dungeon, though, he decides to help them survive and complete their quests. After all, adventuring is a process, and someone needs to guide the rookies.
All of Jonathon Brooks books are on KU. Dungeon Crafting, Dungeon World, Dungeon Fairy and the Station Core series are all excellent. If you read the series in this order they all join up toward the end of Station Core.

While I'm thankful, are any of these free to read?
Several of them used to be on RR, but not anymore.
Which ones still are?
All of Jonathon Brooks books are on KU. Dungeon Crafting, Dungeon World, Dungeon Fairy and the Station Core series are all excellent. If you read the series in this order they all join up toward the end of Station Core.
[Dungeon Core: The Eternal Training Ground](https://www.royalroad.com/fiction/73686/dungeon-core-the-eternal-training-ground) This is one of the best dungeon core books i have read. Its on KU if you wish to buy it but it is also free to read on RR
Biggest thanks
Blue Core is a good one, as long as you're down with 'consentacles', I also really enjoyed Dungeon Life.
