From Introduction:
Included in this supplement are some additional details for the inclusion of the Folks of Faerie in Danse Macabre (2004). Primary information and discussion on Faerie in Benighted Europe can be found in the core rules, and the following details are incidental and optional only.
As the Gamesmaster, be careful before including Faerie Folks and Faerie bargains in a game of Danse Macarbe. Although the Faerie Folk of Benighted Europe are at times bloody, murderous and cunning, their tendencies can be mischievous and capricious too… they are typically good to the good and evil to the evil by nature. Unless subverted by the Unseelie Blight, that creeping cancer sent by Hell to overwhelm Faerie, the Faerie Folks are unpredictable and their laughing, mocking ways can add a very different shade to the fundamentally dark atmosphere of the game.
