Graven

A faithful priest of the Orthogonal order, exiled unto death for a crime in defense of another, you live again in a small boat, adrift in a swamp. A stranger ferries you to solid ground and bestows upon you vague instructions, along with a mysterious staff and book. Go forth, pious priest, alleviate suffering, uncover deceptions, and smash the eldritch perversions encroaching upon reality itself.
