"Revolution" by Jarre could be the theme music for the Ascension Jihad -- Arabian chants against an electronic voice surrounded by fast moving electronic music. It is slightly too modern to suit the overall mood, but as an occasional theme it works.
The magic flute by Mozart is ideal for the hermetic parts of this chronicle. The storyline subtly reflects parts of the chronicle and many of the arias fit in perfectly for the solemn hermetic mood, such as "Es lebe Sarastro", "Wenn Tugend und Gerechtigkeit", "O Isis und Osiris", "Die Strahlen der Sonne vertreiben die Nacht" and "Es siegte die Stärke".
If the cabal succeeds, finish the chronicle with the final choir of Beethoven's 9th symphony, or possibly the final movement of the 5th.
Blue Guide Egypt, Veronica Seton-Williams and Peter Stocks, A& C Black London, WW Norton New York, 1993. Not just a tourist guide but a real reference work for everything egyptian: history, mythology, flora & fauna, religion, architecture, language, practical details, locations (often with maps) and background information.
Focault's Pendulum by Umberto Eco. Gives a humorus and intellectual introduction to the hermetic-conspirative way of thinking, including a secret group seeking a goal just as grand and profound as the Pattern. A must for all Mage Storytellers.
Egyptian Myths by George Hart. Contains several of the most important myths in a form closer to the original stories than the versions commonly found in mythology texts (which have been oversimplified and "cleaned up" to become more comprehensible for modern people).
White Wolf sourcebooks:
Destiny's Price is somewhat relevant for the more gritty sides of Egyptian society; while the underworld works very differently in Cairo and Alexandria human vice and degradation is the same the world across.
Mummy has plenty of information on Egyptian ideas, albeit slanted differently than this chronicle.
Secret Societies for Nephilim by Chaosium contains plenty of ideas for secret societies stretching back from prehistory to the present.
The Complete Golden Dawn System of Magic by Israel Regardie. A huge tome of rituals, essays and diagrams of modern English hermetic magick. Contains several discussions of the Egyptian gods from the hermetic point of view. Not for the faint hearted.
Incense for the more hermetic and ancient sections.
There are plenty of imitation papyri being sold today, with suitably "classic" motifs to be usable. In fact, it is very easy to find ancient Egyptian objects, ranging from the tacky to elegant. Moderation is probably best, but having a figurine on the table might be a good way of setting the mood.
