[Star Wars] Why is older force knowledge sought after? What did they know so long ago that has since been lost?
gpt
Twenty years ago, the Jedi had a massive temple on Coruscant, and were the go-to ambassadors and generals of the Republic. Today, they're regarded as a funny story your grandpa tells when he's been hitting the death sticks too hard.

Basically, no one in the *SW* universe has ever written anything down, and if they did it was in a forbidden language etched into the blade of a giant, impractical dagger. Transfer of knowledge is not great with these folks.

Anyway, there is demonstrable evidence that Force users were more powerful in the Old Old Republic. Yoda and Windu talk about how their ability to foresee future events is crumbling, to the point they might need to inform the Senate that they can't have their back anymore. And on the Sith side of things, they used to be a galactic powerhouse, conquering worlds like some kids collect pogs, or pokemon, or whatever the fuck they're wasting their allowances on these days. Now? The Sith are two guys, one who had a really shitty plastic surgeon, and the other who's a semi-mute cyborg spider demon.

The Force users running around post *RotJ* are piecing together scraps of legend and shreds of lore, trying to figure out why they used to be the most respected - and feared - warriors in the galaxy.
