Of course I have been obsessing over the dagger and the changes to make it ancient. One problem I thought of is, why is Orchi carrying it? If the purpose of the dagger is to lead a person to the way finder … why does he need it? He’s from Exegol. He knows where it is. So why carry it?

So a thought I had was, again, to make this an ancient Sith/dark side thing is to make the dagger’s purpose is for such ones to "find their desire. (Dark side purpose).

Here is the thought. Orchi has the dagger to find Rey’s parents to kill them. For him, although it is an Order from Palps, his desire is to exact revenge on Palpy’s Clone son who “left them, aka the Sith Culture” …which is his personal desire to to kill him for that. Basically, kill him because he is a traitor. So the dagger helped Orchi to find her parents, aka the father who “betrayed” the Sith. (heck, didn’t he even smile before he stabbed them?)

So for Rey, her desire is to find the Wayfinder to lead her to Exegol. She’s already battling the Dark Side and is in ways following it. The movie has already established that’s what she is looking for. So the inscription of the Dagger could be something like:

“The Blade shall speak to the one who walks the dark path to lead them to their desire. Only this blade tells.”

Not that exact wording, but something on those lines. So it 1.) Orchi has a good reason to have it and 2.) Rey will be lead to the Wayfinder, her desire, and having more whispers and visions sells that … the dark side/dagger is showing her the way.
