Cthulhu Mythos 5E - Dark Worlds Act 4

In the fourth and final Act of Dark Worlds, The Green Pyramid, the time has come at last to take the fight to the dread Mi-Go; the Fungi from Yuggoth. Returning to Yuggoth, you find that the Fungi have not been idle in your absence. Can you overcome the Fungi’s might, even with your new allies and eldritch constructs? An epic sacrifice allows ingress to the Pyramid, and you are ultimately led into the Null dimension and confront a being of mindless destruction. The campaign ends by giving you a choice with repercussions that echo across the galaxy.
