The Tower (2006)

from The Introduction:
Winter/spring 1021 AD: the investigators are sent by Stigand, personal chaplain of King Cnut, on a delicate mission to rescue a holy man held hostage by a demon­ worshipper named Quintus. During their secret mission to find Quintus in the Welsh wilderness, the investigators end up in a desolate region, overrun at night by a strange mist. This scenario is the campaign’s turning point, a rite of passage, and the plot is by design more linear than the others. In terms of mood and themes, it draws much on the works of Arthur Machen. We advise the keeper to read Machen’s “the Great God Pan” and “the Three Impostors”. Importantly, investigators who die in this scenario may come back in the sequel. In order to facilitate their return from Limbo, the keeper is advised to stage mysterious deaths, preferably ones that leave no body behind.
