This book picks up where Imperial Age Magick left off.
The Imperial Age: Grimoire covers grimoires, or magickal texts.
Included is information on how to find these books, how to read and use them and what must be done to unlock their secrets.
There are some sample grimoires detailed, with their spells and some secret societies. A lot of information is included here and could easily be adapted to any game. I am thinking of Cthulhu by Gaslight in particular.
Some new and many old OGC spells are also included. They are all by design d20, but can be converted. This makes up a lot of the book, but it is needed.
All in all a great book.
All the Imperial Age books are all well written and features art from the age, either public domain art and paintings as well as some original art. In all cases the art is very evocative of the time and very well done.
The books are all easy to read, with clean layout and font sizes. They can be printed with ease without killing your printer cartridge.
