One Friday Night

This scenario is a one-shot to be played in one session that uses many meta-game concepts and requires some knowledge about the rules of the 7th edition of Call of Cthulhu, so it is only recommended for experienced players. This scenario also requires creativity by the keeper, as it is related to the actual powers that a real keeper has inside an RPG game of Call of Cthulhu. This scenario can be used to close a series of one-shot scenarios (or even a campaign) or it could be considered as a “tournament scenario”, to the extent that it relies more on players’ capacities and knowledge than on investigators’ attributes and skills.
The characters have lived many adventures and have fought many mythos entities (these could be actual adventures or the keeper can make some of them up and describe them to the players). In this scenario some strange things are happening to the world they live in, and the investigators will discover that the pillars of the reality they are living in are very fragile and, in fact, they are part of the mind of a superior being. They will also find out that this could be the last day of their existence and that they have to find out how to avoid their disappearance before the day ends.
