Thanks for taking this question, it has been on my head for some time now.
So, Elidibus sends us to Elpis in Endwalker, during our stay we meet Venat and apparently tell her EVERYTHING so that she can act upon the future and "prevent" the final days, but here's what's been bothering me.

1.- For the WoL to BE there in Elpis it needs that the G'raha from "the original timeline" travels through "time and space" to the first so that he can prevent the WoL and friends from dying to the Black Rose. Do we tell this to Venat as well? And if we do, how does she go down this path exactly? Does she willingly lets us die to the Black Rose so that in the events from Shadowbringers happen again?

2.-If it's not a "closed loop" how exactly did the events in Elpis play out without us there since we couldn't have possibly went there if the Black Rose killed us in the "OG" timeline?

3.-Are there any plans to probably visit the "originalt timeline" in some way (ie: An Ultimate/Minstrel's Ballad/Sidequest) considering Meteion is still there?

4.-How big are the reflections? I know now that each one has its own moon, but how far is it? Are they supposed to be entire universes or does it only include our planet and the moon? If someone from "The First" and from the source travelled to Ultima Thule's location would they meet there or each reflection has it's own version of Ultima Thule?

Thanks
