There are realities other than the mundane one we perceive. Its places, people and occurrences are inexplicable to rational scientific thinking and antithetical to our existence. Ancient lore, monsters, forbidden tomes, and diabolical cults are just the forerunners of the unimaginable entities who dwell in the cosmic void. They are coming for us: our world and our very minds.
Exposure to such horrors can lead to madness, but some bold souls must make a stand against these seemingly insurmountable odds. Defeating them will save the world as we know it; failure will usher in the end times. Can you hear the Call of Cthulhu?
