While we've had two prequel Trek series with Enterprise and Discovery, there's still a pretty big gap in Trek lore-the big gap between TOS (at least from the point of "Generations"'s prologue) and TNG. Of course there have been many novels about it...but nothing as far as TV canon is concerned. Would such a series work in some form?
There's been some details about this era.
-Presumabely the Enterprise-B continued it's voyages, and then the Enterprise C until the events of Yesterday's Enterprise.
-Spock of course becomes an ambassador, and once again has a falling out with his father, reportedly over the Cardassians. Also possible he gets married, although the TNG reference is a bit vague.
-Starfleet seems to move from less of a military role to that of exploration.
-Relaxed relationships with the Klingons, although there is still uneasiness with them nearly sliding into war again around the 2340's (Yesterday's Enterprise)
-The whole thing with the Treaty of Algeron, forbidden cloaking devices for good and causing the Romulans to go quiet again apart from a few skirmishes here and there, notably with the Klingons (Where Worf's birth family was killed) and the Enterprise C.
-Some sort of war with the Cardassians.
-The younger years of TNG's crew, including Picard's Stargazer stuff.
