Based on the H.P. Lovecraft short story of the same name with gameplay based on The Ravens of Thri Sahashri this is a 2 player game taking around 20 minutes. Strange tunes filter through the floor from the garret room above as Erich Zann plays his fiddle all night. But Zann knows not the tunes he plays and the Listener hears them only in his sleep. Neither of them know that they open gates to terrible and hungry dimensions. If they can together master the tune before the threshold is breached then Zann can undo what he has done before it is too late. Players take turns playing asymmetric roles. The Listener places cards into a puzzle tableaux in an attempt to provide Zann with the notes that he needs to complete his tune. If they believe the tunes sufficiently learnt they can break into Zann's garrett room. Too early and the tune will simply find another player, too late and all that is and ever will be are swallowed by the void. —description from the publisher
