The Infested Caverns form a branching underground network of irregular chambers and narrow connecting tunnels, trading predictable dungeon corridors for natural stone and broken sight lines. Wider pockets give encounters room to expand, while tight passages quickly separate characters who move too far ahead. The cave structure itself does most of the tactical work: corners hide what lies beyond them, constricted routes make retreat difficult, and multiple chambers let danger approach from more than one direction.

The expanded preview set gives the caverns enough variation to support exploration rather than a single isolated fight. In Strength of Thousands: Kindled Magic, the infestation provides the immediate problem, but the map remains broadly useful as a creature den, forgotten undercroft or natural cave system beneath a settled area. A GM can use it for cautious scouting, rescue scenes or a sequence of encounters where the party never has a perfectly safe line of sight through the next chamber.
