In the center of a valley that should not be stands a thing that cannot be. Those that go before the Monolith do not return the same as they left. Sometimes they do not return at all. The Monolith is a wild surreal horror adventure for characters of any level, from zero to infinity, for use with Lamentations of the Flame Princess Weird Fantasy Role-Playing and other traditional role-playing games. Writing by James Edward Raggi IV with "The Owls' Service" by Kenneth Hite. All artwork by Aeron Alfrey.
