Well, its not so much a direct part of The Baroque Cycle as a continuation using descendants of the main characters and a lot of shared themes - a bit like Cryptonomicon. However, The Baroque Cycle does have some unusual minor elements such as 'magical' gold and an important character, Enoch Root, who appears to me immortal and who turns up in 17th, 18th, 20th and 21st centuries. Fall gives an explanation of what is going on that I really liked.
