The Great Stone Gears are three interconnected chambers (areas 58, 59, and 60) constructed within massive rotating stone gears on level 5 of the Tomb of the Nine Gods. These chambers represent a dynamic puzzle environment that can be physically reconfigured.
Mechanics
The gear rooms are initially positioned as shown on map 5.5 when characters first arrive at this level. After the initial encounter, the rooms can be rotated using controls located in area 61, allowing players to change the configuration of the chambers.
Construction
The chambers feature a unique architectural design where the ceilings are disconnected from the walls. This allows the rooms to rotate independently without affecting the orientation of the ceilings or the central shaft that runs through area 58. This engineering creates a disorienting and mechanically complex challenge for adventurers navigating this section of the tomb.
