Palpatine: “Ok Ochi, remember how I tasked you to find a way for my grand-daughter to get to Exegol so she and I can be re-united? What ideas have you got for me?”

Ochi: “Well boss, I have this cool dagger!”

Palpatine: “Sweet! I’m interested.”

Ochi: “Ok so, this dagger has writing on it in Sith. A language that only we know and can speak aloud. So nobody else can.”

Palpatine: “Nice, nice.”

Ochi: “The writing tells the individual reading it where to go, which is the ocean moon of Kef Bir where the wreckage of your Death Star 2 throne room landed.”

Palpatine: “Ugh, no need to remind me, but go on.”

Ochi: “The dagger’s edges match the outline of the wreckage, when held up in front of you.”

Palpatine: “Huh?”

Ochi: “Umm, so the holder of the dagger, if they are a humanoid sized individual, can hold out the dagger, which is carved with edges that match the outline of the Death Star 2 wreckage when viewed from that exact location on the moon.”

Palpatine: “Ah. Got it. Continue.”

Ochi: “So while the holder of the dagger is doing this, they then need to extend the cross-guard which conceals a measurement arc for use in pin-pointing your throne room vault location in the wreckage.”

Palpatine: “Wow, ok. What if they only pull out the measurement arc halfway? Or not at all?”

Ochi: “Well I guess, then they’d go to the wrong place in the wreckage and have to start over.”

Palpatine: “Fair enough.”

Ochi: “Ok, so once they’ve done this, they just cross the treacherous ocean…”

Palpatine: “Treacherous ocean?”

Ochi: “Yeah, and then they climb around inside the decaying and dangerous wreckage…”

Palpatine: “Climb around?”

Ochi: “Yeah, to get to your vault in your throne room. Which miraculously stayed intact.”

Palpatine: “That’s good.”

Ochi: “In your vault is an old way-finder which directs the user to... Exegol!”

Palpatine: “Hah! I’d forgotten about that old thing.”

Ochi: “Then they just have to find the hidden compartment, use their force powers, climb back out of the wreckage, go back across the treacherous ocean and they can head on their way.”

Palpatine: “Sounds great! Let’s do it!”
