Shuffle the encounter discard pile into the encounter deck. Then, discard cards from the top until a location is discarded. The lead investigator resolves that location's 'revelation' effect.

Check Campaign Log. If at least one name is recorded under "Sacrificed to Yog-Sothoth," read the following:

"You hear a familiar voice calling out to you, and you enter an impossibly shaped building of cracked stone. "No… don't!" the voice cries. You rush toward the voice, down a set of steep, narrow stairs. Upon reaching the bottom, you find yourself in the hidden chamber from Dunwich. Bound by shackles, you see those you failed to save, bloodied and maimed. A creature with a man's face feeds from a corpse on the ground. The head of the corpse turns to face you, and a sharp pain stabs your heart."

Each investigator tests (X), where X is the number of names recorded under "Sacrificed to Yog-Sothoth." For each point an investigator fails by, that investigator takes 1 damage.
