Quick question. I know that Destiny brough the DS9 lit 5 years forward. Was Titan already their?
Star Trek: Nemesis established that Will Riker had been promoted to captain and assigned to the USS
Titan, an assignment he began immediately after that film. Therefore, naturally, the
Titan novel series begins right at the end of NEM, in November 2379, and proceeds from there into 2380. Soon thereafter,
Articles of the Federation was published and portrayed events involving the Federation President over the course of the whole year 2380. After that, the TNG novels began a post-NEM series also set in 2380.
Therefore, when it was decided to do a massive inter-series crossover event,
Destiny, it made the most sense to put it in the timeframe of TNG, TTN, and AotF, but pushed forward a bit to 2381.
And no,
Destiny did not move DS9 forward.
Destiny moved
Voyager forward, and the VGR relaunch books being developed by Kirsten Beyer were plotted with that in mind; but
Destiny only moved Ezri Dax and a few minor DS9-novel characters forward as crewmembers of the
Aventine, while carefully avoiding mentioning anything else DS9-related. Afterward, when Margaret Clark took over responsibility for the DS9 books, she decided that the series should be brought ahead into synch with the rest so that it wouldn't have to be excluded from the post-NEM continuity in future works.
I'm sure I explained most of this to you in another thread.
What is the time difference between the 4th Titan (pre-Destiny) book and Destiny?
About eight months, June 2380 to February 2381.
Also, what is the time difference between Typhon Pact: Seize the fire and Destiny?
Seize the Fire contains conflicting claims, saying at one point it's about a year after DES, which would be February '82, but saying elsewhere that it's a year after
Titan: Synthesis, which would make it August '82. I've assumed the February setting in some earlier posts, but I've remembered now that Mike Martin told me in personal correspondence that it was meant to be in August.
And, Titan continues have novels produced, can I assume that sales are decent/good for S&S?
As long as they keep putting them out, that's a reasonable assumption.
