A decade ago, a band of occult investigators battled against the summoning of an ancient and monstrous evil. 

They failed.

Now, you must piece together what went wrong. Investigate ancient crypts, abandoned estates, and festering slums. Explore choked jungles and the crushed psyches of your predecessors. Follow in their footprints and make new ones of your own. This time, there won't be another chance.

The world is yours to save or lose
