The thrilling isekai adventure series delves ever deeper as a sentient dungeon core—once human—continues to grow in size, scope . . . and danger. It seems like a lifetime ago that Thedeim was a mortal man. After a fatal accident, he was transported to a strange realm to begin again as a living, low-level dungeon. But he didn't stay small for long. With a powerful will, he built his dungeon self into a force to be reckoned with, full of minions, creepy crawlies, and a hedge maze to die for.
Except Thedeim isn't a place where delvers die. He's a different, friendlier kind of dungeon, which suits both him and his many allies just fine. But being a nice dungeon means taking on some not-so-nice entities.
Now, an enemy of monstrous design is plaguing the realm—and requesting Thedeim's aid. The imminent fight against this mysterious foe will push Thedeim to the limits of his power, his mana, even his humanity. But one thing he knows is how to go beyond his limits. Even if it leads to peril. Or the afterlife . . .
