Will we ever go to this Alternate Future?

[Iscah]

We can't perceive the Bad Future because we didn't experience it. We can't experience (observe) it since, from our perspective, it exists as nothing more than a possibility that never came to be. Whether or not we physically survived is immaterial.

G'raha, on the other hand, did observe it; it's not just a possibility to him. It's very real from his perspective, therefore he should theoretically be able to return to it.

I am still very confused as to how you are picturing this working.

I think you're picturing that to get to the alternate timeline, we have to travel back to somewhere pre-split and then forward along the other path.

I still don't see how that would have any relevance to the version of ourself that dies in the Eighth Calamity. Travelling back in time doesn't revert us to being our earlier self, but puts a second copy of ourself in that earlier world - otherwise G'raha travelling back from the future wouldn't have arrived in the First to become the Exarch, but would have reverted to being his original self still asleep in the tower. Therefore, the survival of our other self has no bearing on our ability to arrive in, or perceive, the other timeline for ourselves.

The statement that "we didn't experience the events of the other timeline so we can't know what it's like" is... inherent. Of course we haven't had our other self's experience but we wouldn't be needing it because we don't need to travel precisely in their footsteps.

We can't simply get to the other timeline by going back in time and "living through" the split in some deliberate manner to take a chosen path. The split itself creates two copies of us - one who is (and always was) part of the bad timeline and one who is part of the good timeline. And still we are a separate entity to our younger self who is fated to die in the Calamity.

The whole thing is horrendously complicated and I still don't know if I'm even understanding your point or arguing against it correctly because I can't understand how time travel could rely on another self's perception instead of our own action of travelling there.

Also, G'raha observed a very small part of that other timeline, nowhere near the point where they diverge. Anything about the events leading to the Calamity are distant history to him, not something he knows in great detail.

In any case if they were ever going to do a plot where we visited the other timeline, they might simply invent some kind of new higher power of travel - closer to Omega's direct navigation across the rift - so there would be no need to navigate back and forth through time to get there. Maybe still forth, after we got there. It's all still terribly messy but as long as we only visited a point after soon-to-be-Exarch G'raha left, we wouldn't actually be risking breaking the timeline because by going to the future, not the past, there is no risk of us doing anything that would contradict our knowledge of the past (and thus trigger a split timeline).

Still. I don't think we're doing it in any case because it would be narratively over-fiddly for the sake of going somewhere that is, narratively speaking, better left unvisited. But you're overcomplicating the reason why it wouldn't work.
