Been away for a bit and got caught up a bit. Ah yes, both Burbin and Captainfaraday brought up those important points about the dagger. A house of cards in deed Jar Jar.

So, the one simple answer is to unfortunately have the dagger specify Endor, but it would certainly remove the idea of the dagger being ancient, which then gets us back to the way it is from the start.

However, to still try to keep the idea of it being ancient, I dunno if your view on this has changed now Hal about having a chosen one/prophesy angle on it, but here is my thought now tying it both these points with Lando (Orchi has a clue on him about the Wayfinder) and the comment about Frik.

The blade can be viewed as something ancient if it does indeed have a “sith prophecy” like the Jedi had about a Chosen One in the PT (that in turn affected the OT, technically speaking)

So the Dagger can have an inscription about “the one to take the throne … Where the Emperor/Sith have fallen … the blade will guide to the Wayfinder.” Again, just something on those lines and can have more specifics since it is a “prophetic” ancient dagger. Something kind of “big deal” like the Chosen One prophecy was a “big deal” to the Jedi. So it could connect with some verbage based on part of Palp’s speech later, or even some of the wording on the “broadcast” people like. I dunno, something like that.

Also, since Hal removed Palp’s explicit intentions with Palpy and Rey (Not saying it was to kill or not, or however) but this could be implied now that Palps sent Orchi, with the Dagger, to see if Rey is either chosen or whatever by the dagger.

People know where the battle of the DSII was and where he “died,” so Frik would have contacted Jannah and them about their arrival.

Again, just initial thoughts and will need to ponder longer.
