The Black Monk, Oubliette

From publisher blurb: In The Black Monk, Oubliette the characters live inside a dark, onyx monestary that’s been turned into a self-made prison. It’s name is Absalom, home to roughly 100 people, all living in fear of the outside world. The outside world. Desolate. A place where time has lost all meaning. A place where a host of unimaginable monsters dwell, including the undying Black Monk — a vile being bent on keeping the inhabitants of Absalom alive just long enough to drive them insane. Whenever the Black Monk visits, the sun disappears and night falls over the valley. The people retreat to the monastery. Whenever the Black Monk leaves, the sun reappears and hangs in the sky for days on end. For hours after, the residents remain, fearing a surprise return of the Black Monk. Inside, the hours drag on. Endlessly. It’s cold. Is this eternity? Or damnation? How are there shadows inside the darkness?
