I've had some thoughts and questions over the years about the future where the Enterprise-J is seen, from the episode "Azati Prime" and thought I'd write them down. I included a transcript of the scene from here. Enterprise J Observation Lounge DANIELS: Welcome aboard, Captain. ARCHER: Daniels. Where am I? DANIELS: You're on Enterprise. Enterprise J to be exact, a distant relative of your ship. We're four hundred years in the future. (There's a battle going on outside in a murky purple haze.) ARCHER: I'm going to assume you brought me here for a good reason. DANIELS: Look out there. It extends fifty thousand light years in all directions, and it is growing. ARCHER: I've seen it before. DANIELS: I know, in the Expanse. ARCHER: You know about the alien we found, the test subject? DANIELS: He belongs to the same race that built the Spheres. They're altering this space to make it habitable for their species. It's a prelude to invasion. ARCHER: We came to the same conclusion. DANIELS: It's getting harder and harder to surprise you, Captain. (the ship shakes from an impact) I've brought you to a monumental moment in history, the battle of Procyon Five, where the Federation engaged the Sphere Builders. ARCHER: The Federation? You've mentioned them before. DANIELS: Vulcans, Andorians, Ithenites, Klingons. Dozens of species, including humans, all unified in a powerful alliance. Sphere Builders. (The large ship is blown to smithereens.) DANIELS: The Federation wins the battle, they drive the enemy back into their trans-dimensional realm. If the Federation had lost, the Sphere Builders would have spread throughout the galaxy. They would have wiped out everything. This species has technology which allows them to examine alternate timelines. They've seen this future and they want to change the outcome, so they contacted the Xindi and convinced them that humanity was a dangerous threat. ARCHER: They want the Xindi to destroy us. DANIELS: Without humanity, the Federation will never exist. You have to make the Xindi understand that humanity isn't the enemy. In fact, it's humanity that will protect them from the Sphere Builders when this battle is won. Contact them. Make peace. ARCHER: They're about to deploy their weapon. DANIELS: I know. ARCHER: I can't let that happen. DANIELS: If you destroy their weapon they will only build another. You are the only one who can convince them of what I have told you. It is crucial to history that you do not sacrifice yourself. ARCHER: My concern is with preventing the deaths of billions of people. If that's a problem for history, then history will have to suffer. DANIELS: Send someone else. ARCHER: I won't do that! DANIELS: Captain, you have to believe me. You are making a catastrophic mistake. ARCHER: You've made your share of mistakes. DANIELS: This isn't one of them. ARCHER: Send me back. Send me back now! DANIELS: Take this. (A coin-sized disc.) DANIELS: It's Xindi. A family medal that belongs to one of the crewmen on this ship. There are Xindi serving aboard Enterprise J. ARCHER: Why are you giving this to me? DANIELS: In case you change your mind. ARCHER: I won't. Is Daniels from this timeline or some other one, or it doesn't really matter? Do you think the real star Procyon is meant to be where the Battle of Procyon V took place? There are similarities with the prime timeline, in that there's a Federation and with there being an NCC-1701-J there would have to have been a NCC-1701 and all ships between, but the specific details could have been a whole bunch difference. There are Klingons in the Federation. Now this could just be references to Worf and other individuals but I like the idea that the whole Klingon Empire became part of the Federation. There are Xindi in Starfleet. The Delphic Exapanse "extends fifty thousand light years in all directions". Isn't a bit odd that the Federation let this thing get so big before dealing with it? Presumably Earth and the Federation are inside the expanse by this point in time. Were the Xindi protecting the sphere network in this timeline too, so it was impossible for the Federation to do anything about it? How long did the Federation fight the Sphere Builders and when did the invasion happen? Were the Sphere Builders defeated as soon as they invaded or was it longer? I know it turns up in Star Trek Online but I'm not a fan or the arc-welding of storylines in that game. It's an interesting timeline to me and reminds me of the Myriad Universes books in potential of giving individuals and organisations quite different outcomes than the ones that actually occurred. Cheers.
