I'm currently reading the Secret History of Star Wars and I came across a point where he discusses the fact that Alan Dean Foster was originally suppose to write two books following Star Wars that would encompase a low budget trilogy in the event that Star Wars didn't do well. But when Star Wars became a hit this idea was scraped and we only got the first of these books, Splinter of the Minds Eye.

I've always been curious what this 3rd part might have consisted of had it ever been made but nobody every seems to talk about it. Does anybody know if there is some information out there regarding what the last book would have entailed?
