It is 1926, and the museum’s exotic curios and occult artifacts open barriers between our world and the elder evils lurking between dimensions. Other Worlds begin to leak through and terrifying creatures of increasing strength steal through them. Animals, the mad, and those of susceptible minds are driven to desperation by the supernatural forces that the portals unleash. In the midst of this chaos, a handful of investigators race against time to locate the eldritch symbols necessary to seal the portals forever and stop evil Ancient Ones from reducing humanity to cinders.
