The Cracked Graal, third in the Lucifer biography series, is science fiction and fact. Eurasian societies have an older Graal account providing a fuller cosmic history than the Graal as the cup of the Last Supper, Mary Magdalene's uterus, or the Mass. The Eurasian "Churning of the Cosmic Ocean" requires a sentient being drink a cup of poison to save the embryonic worlds. Lucifer makes that sacrifice, but a fatal flaw in the Cosmos now needs to be corrected by him. Trapped and confused, falling through levels, gaining sanctuary at the Pendragon level, his existence fades. This prequel relates how Lucifer's sire fights to become Pendragon and produce the Last Pendragon, Lucifer, to perform the impossible task or become the final sacrifice to it.
