The Romulan War took place between 2156-2160, https://memory-alpha.fandom.com/wiki/Earth-Romulan_War . It began 2 years after season 4. Season 4 was in 2154. Jolene Blalock can still play T'Pol. I agree with a series showing from the formation of the Federation onwards. This series should be around the same year as Star Trek: Picard and Star Trek: Lower Decks, maybe also Star Trek: Strange New Worlds, so we get a series in the distant past of the Federation or pre-Federation and a series set in the future. I wish they would do an anthology series.
