The player arrives in the present day, ostensibly to mix corporate duties with the family business of claiming an inheritance, the legacy of an unknown Great Aunt. But your investigations enmesh you with an involved story going back to the frightening witch-hunts that coincided with the English Civil War, traversing the Rebecca Riots, the British Agricultural Revolution and World War II espionage, to the terrible threat that has come to grip the fate of the town following your Aunt's demise. You must discover and assume your Aunt's occult responsibilities - summon allies and new skills - and face the truth that has eluded Castle Avon for nearly four hundred years.
