Weaver of the Cosmos is the sixth expansion in The Dream-Eaters campaign for Arkham Horror: The Card Game.

You did it! You have reached the bridge between realities and the end is near. This place between dimensions is the home of a spider-like creature that will erase the entire world and replace it with a new reality. If you don't stop this creature, there will be no Earth to return to and The Dreamlands will also be lost. You have no choice but to fight...

You have encountered several dangers lately, but none of them compare to this. Atlach-Nacha - the spider-like creature - is enormous, spanning multiple maps and separate from all locations. All of Atlach-Nacha's legs are standalone enemies and can attack investigators at a location. Can you defeat Atlach-Nacha and save the world?
