Was the terrain around Luke's temple different?

"This is a chance to make the sequels disappear or at the very least not matter."

This is 100% delusional. You Locas Loyalists are Coo Coo For Coco Puffs.

They attributed a lot of importance to that baby yoda "choice" scene. I have a feeling Star Wars is going to explore divergent timelines. All stemming from that singular moment. The terrible sequels will still be canon. But so will a new continuity. And they'll probably jump from one timeline to another in some future Star Wars project.

Yeah, the only time we see it is on fire in the dark, so it's difficult to spot any differences when comparing the temple shown in Book of Boba.

Luke's temple is on a different planet than the one he ended up meeting Rey Palpatine on.

Achto is where Luke ended up, but his jedi Academy on another planet was briefly shown burning in a TLJ flashback.
