Can someone help me understand all the time travel?
Future guy is allegedly from the 2800s
Crewman daniels is from the 3000s
the sphere builders are from the 1200s
the temporal war took place in 2900s, but also a separate war with the sphere builders took place in the 2600s?
The temporal accords were signed in the 2700s
and time travel was made illegal by the 3100s (I assume we don't have a date on this one).
Is this all correct?
Future Guy was from the 28th Century, so 2700s.
The Temporal Accords banned time travel outside of science & observation. The Federation of the 3000s was a belligerent in the Temporal Wars to enforce the Temporal Accords. The war itself was fought across time & space, so it is better to think of each time period being fought over as battlefields rather than as a linear progression of events.
The battles in the 2550s between the Federation and the Sphere Builders is all about the trans-dimensional beings invading the galaxy and the Federation repelling them, which pushes them to join the temporal (cold) war (so they can eliminate the Federation and thus have a free hand when they invade in the 2500s).
But clearly, the war was done and over with by the time the Burn happened, and all time travel was banned before then - otherwise why wouldn't Daniels or some other temporal agent just find where the Burn happened and stop it before it happens?
Also, you cannot forget about the Na'kuhl, from the 2800s, who hated the Temporal Accords, escaped captivity and joined the war.
There are other factions likely to be involved with the Cold War, like the Romulans (seen in SNW) and the Q and Borg (fan speculation). El-Aurians are often speculated as also playing a role, either directly (as seen with their opposition to the Q) or indirectly (as pawns in a larger game, that ended with their species' sudden assimilation by the Borg).
