This grimoire presents a really interesting approach to Left-Hand Path magick in that it explores Abaddon through a diversity of individualistic gnosis. My work is Apollyon explores the hidden history, etymology, and mythology of Abaddon. I strongly recommend this compendium — not just because I contributed to it — but because it provides an excellent study on how to approach Abaddon in your own unique magickal way. Every author reveals how they have explored Abaddon and uniquely adapted his energies, his deific masks, to their own initiatory practices.
