The Shadow Over Stillwater is a three-part campaign:
Part 1: Lazarus, in Spades, the first scenario in the campaign, sends the investigators to Stillwater, New Mexico. Stillwater’s sheriff has alerted the authorities that a wanted man, Hank Hanratty, has been spotted in the town. The investigators are hired to the outlaw but, on arrival in Stillwater, they are faced with a situation that threatens to plunge them into chaos and death.
Part 2: Trouble on Knife Cut Mesa immediately follows with the investigators heading to the mesa north of Stillwater to seek the source of recent strange events where a band of Mescalero Apache may aid or confuse their investigation. Tracing their quarry into mountains, the investigators come face to face with an ancient evil.
Part 3: Shattered Earth, Poisoned Sky brings the campaign to a potentially explosive finale. Santa Rosita has been wracked with earthquakes—the residents fear that their town will soon be destroyed. The investigators’ efforts to uncover the secret behind the situation may be hampered by the growing paranoia among the townsfolk. The investigators must delve deeply to thwart a plan designed to remake the Earth.
