In this volume, Carl, Donut, and their growing alliance descend to the dungeon’s fourth floor, known as The Iron Tangle.
Instead of traditional fantasy landscapes, this floor is a mind-bending, impossibly complex labyrinth constructed from the subterranean subway and rail systems of countless conquered worlds. Space, distance, and direction are entirely warped—up is down, close is far, and the exit stairs are mathematically isolated. To survive and progress, the characters must navigate moving trains, perilous transfer stations, and corporate-sponsored traps, all while dealing with a newly introduced “bounty system” designed by the alien showrunners to turn the remaining human crawlers against each other.
