...appears in five volumes at $14.99 a piece. You didn't know Moore had a course on Magick? Yep, it's a series of graphic novels entitled Promethea and it is wonderful.
Basically Moore disguises his teachings/theories as a slightly futurist superhero comic following protagonist Sophie Bangs as she comes to grips with being chosen to be the new incarnation of ancient god/force Promethea, essentially The Scarlet Women. The entire series is packed with Magick, however the real gem is from issue 12 to about 20 where Moore walks Sophie through the Kabbalistic Tree of Life, the ancient map of the Universe that the Tarot of the Egyptians is based on. It is brilliantly rendered in word and in art, J.H. Williams III and Mick Gray really pulling out all the stops and bringing each Sephira to life with the different colors, images and other associations.
In keeping with this, more for my own benefit really, because writing stuff like this helps me consolidate and streamline my own understanding, I'm going to write out the Major Arcana and brief definitions according to Moore.
