Grimoire is a project aimed at providing a set of tools for players of the game "Magic: The Gathering". The tools will help players to manager their cards and decks.
Considered by some to be the same book as the Witches Book of Shadows, but by others as a separate book. The Grimoire to some is that book containing only the practicalities of magick and ritual. If this argument is accepted, then it would only contain spells, formulas, rituals and correspondences. It would not contain poems or personal laments and inspirations.
A magickal workbook or Book of Shadows that contains rituals, magickal meanings of objects, etc.
