Grimoire

[Michiko]

A [grimoire] is a book that contains magic spells to invoke spirits, angels, demons and [demigods] into our plane of existence. The skilled [magician] calls forth these entities to usually make them do their bidding. A grimoire should not be taken lightly. Though it is complete with a guide for the rituals, none but an experienced magician should use it. Grimoires usually possess [hazy] information which is to confuse and discourage the inexperienced. There are many grimoires found around the world. They are even published and can be ordered online nowadays.
One of the most well known grimoires is the [Grimoire] of Armadel
