Liber Umbrarum : Book of Shadows

Liber Umbrarum is a complete six-month system of practice for conjuration of elemental spirits, demons, planetary archangels, and the Holy Guardian Angel. The practice is a synthesis of material from the Abramelin, the Key of Solomon and the Heptameron, with elements from the Arbatel, The Magus and the writings of Eliphas Levi.
