I want a Star Trek show that takes place 3000 years after the events of the original series, and it follows an archeologist who just keeps finding evidence of Starfleet ships that broke the prime directive. It starts with her own culture, who worshiped the enterprise until like, 100 years before the start of the series and she keeps finding evidence of Starfleet having fucked up on underdeveloped worlds that are now spacefaring.
There is exactly one (1) time travel episode and instead of being in awe of meeting the people she's studied, she's pissed off and lectures them about unethical space travel.
In this episode, shenanigans happen, and a planet is in danger, and she realises why they broke the prime directive so often. and begs them to save a planet.
Prime directive is broken, she's the reason, and it turns out it was her planet. It's her fault. She spends the rest of the season having an existential crisis.
