Undo Forbidden Knowledge

A cemetery in the swamp near Arkham, July 1923: A man is his twenties is standing next to an open crypt, a horrified expression on his face. The meager light of his lantern reveals a set of stairs leading into the depths of a dark and foul-smelling crypt. Next to him are a backpack, a spade, and a portable telephone, with its cable leading down the stairs into the darkness. "Get out! Push back the grave slab and RUN!" cries a panicked voice through the receiver. "I can't leave you, Harley," he answers in a trembling voice. "Harley, can you hear me?", he screams. A cracking noise over the receiver makes him pause. Then a hollow, gelatinous, disembodied voice echoes through the receiver: "YOU FOOL, HARLEY IS DEAD." The man begins laughing hysterically. To protect his sanity, his heart stops and he drops down dead.

As players travel through the dead man's past and try to give him a future, they gradually explore a horrifying story that is not from this earth.
