The Rock Demons Ravine

The Rock Demons Ravine was a massive fissure in the center of Screetown, created by repeated impacts from diseased chunks of the New Sanctaphrax rock. The rock-demons resided at the bottom, eating the Librarian Knights lowered into the crevice by the Guardians of Night.

During the events of Vox, the Guardians of Night secretly dug a tunnel from the Rock Demons Ravine into the sewers of Undertown, intending for the rock-demons to invade the Great Storm Chamber Library and kill all of the Librarians Academic. However, when the rock-demons finally entered the library, the Librarians had all left, and the monsters instead devoured the battling armies of goblins and shrykes who had also invaded the Great Storm Chamber Library.
