The fifth floor offers Carl and his team a stark bargain: four castles in fifteen days, with the stairwell unlocking only if they capture each one. Their territory is a bubble containing a floating fortress held by warrior gnomes, a sand-built castle, a derelict submarine watched over by malfunctioning machines, and a haunted crypt laced with lethal traps.

An alliance under pressure

This time, Carl and his companions cannot manage the challenge alone. They must work with lower-level crawlers caught in the same bubble, turning cooperation into a practical necessity—and trust into an open question as they try to advance through the dungeon.

The dungeon is also the setting of a galaxy-wide game show, where the next surprise is never far away. This fourth Dungeon Crawler Carl novel combines a timed, multi-part quest with the uncertainty of relying on unfamiliar allies.
