The Abyssal Angels: Infernal Colopatiron Redux is a stripped-down-for-public-consumption version of the limited edition grimoire Infernal Colopatiron. While the paperback version doesn't include the more dangerous parts of the text, nor the detailed intricate instructions, it does give the advanced magician enough information about gate opening, theophany, and magick to facilitate personal experimentation. The Nuctemeron Gates is a good companion for this text. Publisher's Note: This text does not include some commentary, one chapter, and two key rituals from the original Infernal Colopatiron, all of which will never see a reprint.
