That flaming column was spouting volcanically. The combustion does not lay warmth, but only the clamminess of death and corruption.
-The Festival, H.P. Lovecraft, 1923

In the unimaginable darkness of Kingsport, silent wanderers are called to a profane celebration. Their goal: to invoke unthinkable horrors! A dread terror that is not of this world or any other - but rather from the spaces between the stars - demands your submission. Meanwhile, unwary investigators vainly attempt to halt this appalling chapter in the dark history of Arkham.

As the high priest of one of these shadowy cults, you must dominate the city. You will invoke cosmic creatures and unholy gods to receive their "gifts", but you must take care to preserve your sanity and thwart the investigators who seek to stop you. This time, you are the bad guys. Why settle for the lesser evil?
