Coghead is a story based deep underground, centuries after the surface world fell. Over the course of many generations the last remnants of humanity have forgotten the surface exists and now scavenge the world below for anything that might help them keep their underground society alive. However, once the habitable zones begin failing one after the other, some scavengers would have to begin venturing farther than they previously had in order to save their home. So far that even the forgotten secrets of the old surface begin to come to light once more.
