The Cave of Boll

A cave which leads to the underdark, wherein demons roam and the souls of those that associated with them lay in torment. It is said that some view the gods with pure hate, and view humans as mere tools for their disposal- To such ends they will force many into servitude after death, putting them into the bodies of feral tieflings and forcing them to live and die, over and over until their minds rot out of their skull, only to be replaced by another as the cycle begins anew. Afterwhich their spirit is unceremoniously devoured by hordes of rabid beasts. Not all Tieflings are like this, but those that are provide enough reason in and of themselves to be cautious.
