An extremely important tool employed by the
Ghostbusters in their search for and elimination of
supernatural entities.
Though it is uncertain how old the
Spirit Guide is, it seems to contain every known and surviving piece of information on anything even remotely
occult related. Ranging from how to dispel
zombies, cure
werewolves and stop a
headless horseman all the way up to
Gozer,
Vigo and the
Necronomicon, the guide is indispensible to both the original
Ghostbusters and the newer incarnation
Ghostbusters Extreme.
A new version of the Guide is being compiled by
Egon Spengler for use by the
Ghostbusters Extreme under the title of
Spengler's Spirit Guide
The guide itself is referenced in both
Ghostbusters and
Ghostbusters II as well as almost every episode of
The Real Ghostbusters.
