Quick rough draft idea of the translation based on my concept to make it so the dagger isn’t specifically tied to the Wayfinder. This helps give a reason why Orchi has it and why Rey needs it. To help ease both Rey and the audience, I am using the words: Sith/Way/Finder which also plants the idea in our minds, subconsciously. Again, rough draft and hopefully not to wordy to fit the scene with C3p0 (how long is it and how many words?)

“Only this blade will guide the Sith,
Who choose the dark path to find their Way,
For your heart’s desire, the blade is the Finder,
Your path may be revealed if you heed the calling,
If it accepts your hand, Only this blade tells.”

Again, I wanted it to be not specifically connected to the Wayfinder and thus, Orchi is using it for his mission. Also, I added the “hand part” so part of her vision can be Kylo/Ben which can cut to the part she says “no!” and then the flashes of the Wayfinder. Again, we have Sith/Way/Finder in her mind and ours.
