I hope thou wilt not think the question impertinent, but did thy people's famed longevity perchance play a part in the emperor's decision to entrust this mission unto thee and thine?

That was one reason, yes. We Viis would easily live to see three of your elven lifetimes."
Ah. I misremembered then. I've since moved past to complete the story, but the question wouldn't leave me alone until I tried to solve it lol.

So if an Elezen lives around 120 years then that's around 360 years at minimum, barring getting yourself killed by something. If we go with the idea that they're 'young' women until around 200 before they start actually getting out of that youthful 20-30 something age then 360-400 average seems reasonable.
