The Golden Grimbor is a book of magic containing various spells.
A copy of the Golden Grimbor can be found in the library of the Micawb Mansion. It came into use when The Basement Entity animated several of the other books in the library. Ray Stantz grabbed the Grimbor and found a spell that could return the books to normal without the Ghostbusters having to blast them and cause some property damage.
