Compendium

A Glimpse of the Magic Inside

• Advice on Expanding Magic in your game: the suggestions within this chapter are intended to provide Keepers with ideas and possible scenario plots with which to confound, delight, and horrify their players. Whether ley lines, areas exposed to magical residue, astrological alignments, or other factors, Keepers are encouraged to expand the use of magic within their games, ensuring that "magic" is never a safe, easy, or understandable process, and that it often comes with unforeseen and dire consequences.
• Spells that should not be cast: your investigators will face cultists willing to sacrifice their sanity and indeed their very souls to be able to cast terrible spells in the name of their dark and unforgiving masters.
• And how to integrate Folk Magic (or not).
