Alan Miller (better known as Christopher Hyatt; PhD.) was an author, mage, philosopher, A-1 asshole and Magnificent Bastard.
Off hand I can't think of anyone who did more to advance the philosophy of post-modern Luciferianism over the last couple of decades.
He'll be missed.
(luckily, there's still several of his books I haven't read. So, for me, there's still more new Hyatt to come.)
