An Elfin Book of Spirits contains the sigil and description of 360 spirits, one for each degree of the Zodiac, that can be summoned by evocation to help the magician with whatever he or she desires. It also reveals a system for using stones to find a spirit at random, which is what the authors most often do when seeking the aide of a spirit. These are Elfin spirits, so they command the powers and influences of Faerie and in addition to helping the conjuror fulfill his/her Will, they will also ever seek to guide the magician to the fulfillment of her/his Destiny and the progress toward the perfection of his/her True S'elf.
