A cemetery in the swamp, July 30, 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, whose wire leads 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. His gaze shifts to the heavy grave slab they pushed aside. “Harley, can you hear me?” he screams. A crackling 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.In UNDO - Forbidden Knowledge tragedy strikes on a graveyard in a swamp, in 1923’s City of Arkham: A man, standing by an open crypt, realizes the existence of something so terrifying that, in shock, he suffers an immediate cardiac arrest.
