Cavedweller

Forced into cave are these previous people, but over time they slowly rot and turn into these things of nightmares.  Though there brains can only process basic functions and have lost all common language it still is keeping the creature alive.  It’s ares grow and become clawed so they can climb a top the ceiling if a cave or burrow beneath it.  Besides it’s only speech been undercommon, to speak with other Cavedwellers it makes different pitch clicks, this also allows them to map out caves and to find intruders of there homes.  They are hostile to anybody who is not there own and will fiercely attack them, causing other Cavedwellers to hear and find the commotion to help it’s own.
