"The Lurker at the Threshold"
When 3 Mysteries have been solved, investigators win the game.
The players have 14 spaces on the Doom counter before Yog-Sothoth awakens.
For eons, sorcerers have called upon the power of Yog-Sothoth to bend reality to their will. This incomprehensible Ancient One exists parallel to all places and times, but is bound to the space between dimensions. Gates between worlds continue to open with more frequency and soon, Yog-Sothoth will be free.
If you defeat this monster during a Combat Encounter, lose 1 Sanity and gain 1 Spell.
Set aside all Yog-Sothoth Special Encounter cards.
