The missing mood in the existential horror of the last zone of the game (spoilers)

[Loggos]

Maybe somebody can help me out but didn't they establish that time flows differently in Sphene's reflection, just like it did in The First? And the reason why the time in the dome in Tural passes faster was due to it being part of said reflection?

The Unlost world is part of Sphene's reflection as well, so here time should also pass faster, shouldn't it? Yet Krile's parents say only 20 years have passed.

I don't quite remember how much time has passed between the appearance of the dome and our character entering but it was a few days at best, whereas within the dome it was 30 years.

That means, when Krile Krile was brought to our world 20 years ago, shouldn't that translate to roughly 100k - 200k years in Sphene's reflection?
If we assume 1 day has passed (i.e. 30 years "Sphene time") = 365 days (our time) * 30 years (Sphene time) = 10,950 years in Sphene's reflection for 1 year of our reflection.

Now, 10,950 years * 20 (time since Krile's arrival) = 219,000 years in Sphene's reflection...

If this is true and I haven't made a huge mistake here, then a lot of the endless have most likely lived much longer than any normal Eorzean.

Not sure if it really was 1 day, so this is just an example but the point is, no matter if it was 1, 2 or 3 days... since the Unlost World lies in Sphene's reflection it should not just have been 20 years for Krile's parents. It should have been much, much longer...

Did nobody go over the story's consistency...

Either way, since time seems to pass faster in some way it can probably be assumed that a fair share of the endless have lived many times the lives normal Eorzeans have. Whereas this doesn't make deleting them that much better, we are deleting people who have lived much, much longer and happier lives than the people in the world Sphene is about to destroy.
This goes back to my initial point of them not having the right to be (quasi-)immortal at the cost of others.

Like I said, that doesn't make erasing them good but I do think there is a difference between preserving the individuals of a short-lived species who only have so much time and people who have already experienced centuries, perhaps even eons, of happiness.
We also see that it doesn't seem to cause them any pain. They just cease to exist from one moment to the next, which I also think is at least a bit different from how mortals die and what pain and fear (if being aware) this can entail.
All in all, it seems a little like a send off after accepting that they have "had their (very, very long and happy) fill" and it is time to move on (esp. because they do seem to somehow end up in the life stream again), so that the rest, whose life they'd otherwise have to vampirise, gets a chance to live.

If my assumption and calculation is right. But I have probably overlooked something, haven't I?

Edit because post limit:

I honestly think they just outright forgot the time dilation thing after they used it for the Zooral Ja time skip.

That aside, that would also open up a few more can of worms.

• At what point did someone live "enough" for them to have to step aside for those that haven't? Viera live for hundreds of years. Should they? Do we have the right to decide?
• Do the Endless people know - and I mean informedly know - the price of their extended afterlife?
• Knowing the price, would they still choose to keep living? We know they don't have the choice, but we're not giving them one either.

I don't think that there is inherently a point where somebody has lived enough but I do think that you can measure the fairness of it relative to those who will be killed by Sphene.

If you have already lived hundreds or thousands of years in pure bliss and you are about to obliterate people who live much, much shorter lives only so you can live even longer then I think it's justified to say "you have had your fill (and you lived in such a paradise, you've probably been happier than most of your victims will ever be)". "You" (or your leader, whether you want it or not) don't get to murder whole worlds so you can live longer while robbing them of their shot of at least a short life.

Vieras don't live long at the expense of anybody else.

You are right that they didn't choose this and perhaps they wouldn't condone what Sphene is doing, so the blame completely lies with her.

But this brings up a new question: Does it make a difference if they know, when the outcome is the same? Genocide of one, possibly many, many more worlds?
Of course if there is a way to save them, then this should definitely happen. But if we follow the game's premise that it's just not possible then I think the victims deserve the fairness I mentioned above.

(But yeah, this is all obv. completely speculative because it hinges on the assumption of time passing much faster.)
