So, I've been giving myself aneurysms trying to slowly piece together the new alternate timeline for Star Trek in hopes of running a campaign at some point. Here's what I've got so far with a lot more that needs typed up.
Here's some facts so far:
According to backstory, during the time between Nero showing up to wax the Kelvin and him actually catching Spock, Nero and his crew were captured and imprisoned by the Klingons on Rura Penthe. When they finally escaped, the Narada took them to V'ger. Apparently, after the destruction of Romulas in the Prime timeline, Nero took the ship to the Romulan's secret Borg research place and refitted his simple mining ship into the giant doom vessel we know it as. Nero then uses V'ger to calculate when and where Spock will emerge. There is also one story that claims that V'ger made the Borg has a means of assimiliating more knowledge more quickly. In any case, there's some connection between the two.
Fast forward to the end of the movie and my current plot thoughts:
Since V'ger was programmed to learn everything, it would stand to reason that while it was near the Narada, it would tap into it and drain everything it could from the databanks. Therefore, it would stand to reason that V'ger would have some, if not fairly complete knowledge of the original Prime timeline. That raises the question then, assuming the above is true, what would V'ger do now?
Would it race off to the Delta Quandrant to stop the Borg, knowing what they will become?
Will it return to Earth early in order to provide them with the knowledge it has gained of the alternate timeline?
Does V'ger attempt to go commune with the Q Continuum?
What impact does all of this have on Gary Mitchell (read Q-Squared) and Q?
Do Federation scientists, studying leftover bits of the advanced Romulan technology discover similarities between it and the Borg tech that Zephram Cochrane had as a result of First Contact and/or Capt. Archer's encounter with the Borg during "Enterprise?"
If said similarities are found, how does that further change the timeline?
What does the destruction of Vulcan at the hands of a Romulan do for overall Vulcan/Romulan relations?
Does Future Spock use this knowledge to attempt to complete his goal of reunifying the two species?
Are the Borg of this timeline sent a message from the Narada before it is destroyed? If so, what does it contain?
So, here are some additional thoughts.
1) At the minimum, the Narada would contain the Romulan perspective on everything that has happened in the Prime Timeline as well as any major events, ie. the Dominion and various other wars, the Borg, etc. V-Ger would access that data and immediately begin returning to Earth in order to meet "the creator." Upon arriving there, V-Ger would once again mind-meld with Spock-Prime. The question is, then what?
2) Given that both the Federation and the Klingons have taken losses to their fleets due to Nero, the Romulans emerge from seclusion early. They conduct negotiations with the Orion Syndicate to begin attacking the Klingons. The Orions are primarily tasked with occupying the Federation to keep them from aiding the Klingons. The Romulans begin attacking Klingon outposts with their new Bird of Prey (see Battle of Icarus IV).
3) With the changes going about the Alpha Quadrant, Starfleet starts getting pressured to become more militant. Under Admiral Pike, Starfleet forms it's new Strategic Operations Command tasked with overseeing the increased military presence to be established. Meanwhile, the remnants of the Vulcan Science Academy take over a section of Starfleet Academy on Earth and help establish the Federation Science and Exploration Council.
4) Several months after the Battle of Vulcan, Federation scientists, studying the remains of the plasma drill left from the Narada make a startling discovery. The technology in that device has many similarities to the crashed spaceship discovered in 2153 (the Borg Sphere from First Contact.) A new joint venture between Strategic Operations and the Science Council begins studying the technology more indepth, hoping to be better prepared for when the strange cybernetic aliens finally reappear. The shipyards at Utopia Planetia begin to develop a new extreme long-range scout/science vessel to explore towards the Delta Quadrant and hope to establish an early warning. Members of the Vissian scientific community are also brought in to help develop omicron radiation based weapons in hope they will prove more effective based on the reports of Dr. Phlox during his tenure as Chief Medical Officer aboard the Enterprise.
