"Call of the Void" picks up where "Call of the Machine" leaves off. With our protagonist trapped in the void, suddenly, they hear a voice in their mind. The entity speaking identifies itself as one of the ancient gods Vadrigar, who proposes to the protagonist to escape the void by sending them on a new mission for revenge against the Stroggs. This is in response to the Stroggs transforming the fallen Vadrigars (Chton and Shub Niggurath) and their followers into partially mechanical creatures in the service of the Strogg leader Makron.
