The Universe of Magic
Magic cannot be contained or easily defined. It can barely be controlled. It is large, omnipresent, and multi-faceted. It contains multitudes.
A few of those multitudes are in this book, such as Pierre Dubois, media personality and Psionist researcher; a band of fortune seekers known as Treasure Hunters, Inc.; strange crystalline entities who may be forming a dangerous alliance; a spell to turn an unfortunate victim’s blood into a sludgy mess; and an adept power that temporarily blanks out memory, making an individual immune to interrogation.
These and more are here—spells, adept powers, rituals, and a host of magical knowledge. It may be a single meter would compared to the nigh-infinite length of the full scroll of magical knowledge, but as any shadowrunner can tell you, in a pinch a meter can make all the difference in the world.
Shadow Spells is for use with Shadowrun, Fifth Edition.
