At the bottom of Yeesha's letter that she left on her father's desk in K'veer, there are three numbers:

3118
245 -55

To me, that looked like the same type of coordinates I had been following through To D'ni to get the Rezeero working again.

There was a bonus set of coordinates in Sharper's journal, a little gift from Zandi. The coordinates led you to jump off the side of a cliff. That was easy enough to find.

But I cannot find those coordinates that Yeesha wrote on that final letter. Does anybody know where they are? Or if they even are coordinates at all? If they're not, what are those numbers, because this has been bugging me for a while now.

Have you visited the Great Zero yet?

I'm doing a replay; (Where I'm strugging against one of the dumber puzzles in the Eder sets) and if your KI isn't exactly coordinated, figuring any of that out may be a bit tricky.

If you'd prefer a straight walk-though, I could fetch one.

Ah, of course. Myst has a lot of puzzles that go wrong if you've got your head tilted. Happened to me as well.
