3,000 years before the birth of Christ, fearful tribesmen raised bloody sacrifices on the Salisbury Plain in honor of a dread god. The skies coursed red with blood, consuming the weak, granting boons to the strong, and seeding ghastly young in the wooded glens about the Salisbury Plain.

50 years after the death of Christ, the Roman legion Legio IX Hispana, led by Gnaeus Hosidius Geta, swept through the region, slaughtering the indigenous Celtic tribesmen. Those that stole the religious artifacts soon succumbed to madness, and the legion vanished from the annals of time.

Present day, 1928: Misguided worshippers seeks to call forth the patron god of old. The dark god will stride across the Salisbury Plain once more, and madness is sure to follow.
