If there are no investigators at Cthulhu's location, discard this card and draw the top card of the Cthulhu deck.

Otherwise, each investigator at Cthulhu's location tests (X), where X is Cthulhu's Rage. If 1 or more investigators fail, discard cards from the top of the encounter deck until an enemy is discarded and spawn it at Cthulhu's location.
