Cactus's wonderful vague explanation of how the hell this is possible is somewhat covered with this comic. The great round-about mythos of Genrezvous Point is the perfect vehicle for offbeat meta-reality.
A word on the good Abbé Faria. 80%-90% of his dialogue is obviously directly adapted from "The Count of Monte Cristo" and as a writer, it's an interesting exercise in adaptation. I don't get to do it very often, but fun as hell.
