The Clicking Caverns are set of underground tunnels and caverns known to connect to the Darklands of the continent of Tian Xia and are located on the border between the nations of Xa Hoi and Nagajor. They are inhabited by clockwork constructs haunted by the souls of their extinct builders.
In -395 AR, the haunted clockworks poured from the Clicking Caverns and attacked both Xa Hoi and Nagajor. In 4708 AR, the nagaji hero Zethivaxus Djeed led an ill-advised expedition into the Clicking Caverns, and later emerged as a haunted clockwork himself in an invasion of the highlands of western Xa Hoi.
