Add a subrule to “Artifacts” called “Scrying”:-

As a weekly action, a Believer (the “Scryer”) may attempt to Scry the date of the end of the world using a number of Artifacts that they have access to, by submitting an Order which names the Cults whose Artifacts they will use in the ritual, and the number of Artifacts they will use (the “Components”).

If the total number of Artifacts belonging to those Cults is less than the specified number of Components, then the Scrying fails. If the Order names a Cult that the Scryer does not belong to, or a Cult where another member has a higher Insight than the Scryer, then the Scrying fails. In either of these cases, the Scryer is informed that the Scrying has failed.

Upon processing such an Order where the Scrying does not fail, the Auspex shall select X random, distinct days between the 15th and 31st of January, excluding Doomsday, where X is the number of Components (or 10, whichever number is smaller). The Scryer shall then be informed of these days.
