Saving the Void? (Time travel) - future expansion idea?

[Iscah]

Considering how Yoshi-P basically mentioned things were going to get frantic after 5.3

I saw someone say that was meant to be translated as "the second half of Shadowbringers" which might mean patches or might be 5.0 itself. The story certainly got pretty frantic on major lore reveals in its second half.

There is also the possibility of those fragments being absorbed as a result of the WoL killing their other selves. Should be theoretically possible since they wouldn't be fighting on even footing anymore. That whole rejoining with Ardbert thing gives an edge up.

It would be completely at odds with the ideals of the story and everything we've done so far. How could we possibly justify killing our other selves violently, in a narrative where the heroes place emphasis on the value of individuals, and on not sacrificing people for causes?
