13 years ago, the Cult of Cthulhu attempted to summon a great being from the netherworld. Unfortunately, they made the worst mistake possible. They succeeded.

The only survivor of the summoning was a lady known as Old Mimi. She founded The Cult of the Children of Cthulhu, and made her own following. Over the 13 years since the founding of the Cult, Old Mimi has gathered followers, perfected spells, and waited for the perfect time to enact the most powerful summoning spell ever attempted -- the night of the winter solstice. Tonight, members of the Cult gather at Old Mimi's cabin in the woods to summon a great demon, bind it, and obtain its powers. Tonight, you will become a god.
