Here is why I think this translation could work if we are changing the context of the dagger:
“The path to rebirth begins where our Emperor died. Heir of the Sith, embrace the darkness within. Only to you will this blade tell.”
“The path to rebirth begins where our Emperor died.” - C-3P0 would/should immediately know this is Death Star II, which remains are on Endor.
“Heir of the Sith, embrace the darkness within.” - Calls upon Rey to go to the dark and further conflict her in the movie, when she goes into the vault she sees what that darkness would lead to i.e. Dark Rey
"Only to you will this blade tell.” - The blade will only show the path to the person that is the Heir to the Sith. This could work for Rey Palpatine or Rey Nobody. Rey Palpatine, there is a blood connection to Palpatine. Rey Nobody, only someone who embraces the dark side can use it.
I mean, it sounds nice in the original context of the film, but aren’t we trying to avoid that? It tells Rey exactly where to look, just based on the inscription. Who needs the physical dagger?
The purpose of the physical dagger was that it would show you the location of the wayfinder when you actually get to the location. Poe says that it would take years to scour the wreckage. In all of this convoluted stuff you guys are missing the point of the dagger itself.
It works best that the dagger whispers to Rey when she is in its proximity. If it does it anytime before then, then the question easily becomes this: why didn’t she just use the dagger to get to Endor in the first place? When it was stolen, they should have gone after it. 3P0 wasn’t needed, and so Kijimi was a waste. It makes the characters seem not that bright.
I can’t be the only one to see how potentially problematic these suggested changes are.
