I'm only on the second of 6 (to date) so I can't answer all the questions yet! I don't think that the British had abolished slavery in 1831 from what I have gathered but in the 1930s they are a major force in trying to stop it. The Crimean war has not been mentioned. Neither Britain nor Russia have had a great part in the series as yet, although both empires are mentioned. The French are worried about the threat from the Ottoman empire and from both Germany and Russia. Sorcery does work and seems very Cabalistic up to now. No real mention of Islamic science but as the story hinges around the Grail and stems from the Knights Templar and the crusades there are hints at what was uncovered in Solomons temple by both Christian and Islamic forces.

Unless you are a comic book and fantasy fan they probably would not work for you. If you are they are a masterpiece:-) My favourite is still a comic book I have which depicts some famous folk ballads as comic strips - Can't remember the title but it will come to me. Eventualy!

Cheers
