Echo Mine

Nestled in a valley in the Mekillot Mountains, this ancient silver mine might hold untapped riches. Many expeditions have sought to reopen the Echoing Mine, but all have discovered to their cost how the place earned its name. Hook horrors, grimlocks, and other light-hating subterranean monsters infest the tunnel system. The mysterious clicks that echo through the mine are the rapid, high pitched sounds these creatures use to navigate and communicate.
