The claimants' ages

[Fenral]

I hesitate to chime in because I can't recall the specific instance either, but I remember there being a line where Wuk Lamat mentions that an event 20 years earlier took place before she was born. So, 19 at the oldest, but possibly closer to 17, depending on how broadly her age was being compared to Alisaie's.

I remember that as well. If we take Yoshida's comment about roughly two years having passed in-story since ARR, they can both be assumed to be approximately 19. (The Elezen delayed puberty is the likely handwave for why the twins' models haven't changed at all.)

But time and ages are funky by default, since the amount of time we've spent just traveling on boats should already be around a year. Tech level varies wildly based on whatever looks good, so the crossing to Tural alone could have taken anywhere from two months to a week, never mind the trip from Limsa Lominsa to Kugane in Stormblood (assuming near-Earth distances). (Characters are very inconsistent about Aetheryte usage, too. They were crucial in Endwalker, but in Dawntrail there are several references to returning by boat, which seems silly for all the references to aetheryte technology.)

But the 20 year measurement itself could involve some rounding up or down, since we have both an event from 20 years ago where Wuk Lamat was around, and one where she wasn't.

"Years ago" and ages are measured from ARR regardless of how much time has actually passed.

During A Father's Grief main scenario quest, Wuk Lamat has optional dialogue where she says "So Hunmu Rruk has been Xbr'aax Rax for over twenty years... That's before I was even born!", so I thought she was like ~18, 19 range? Or just 20 since she does say its over 20 years.

That's the one! Thank you. Based on that phrasing, I'd say she's definitely under 20.

I forget where the dialogue specifically is... But I recall someone saying that Wuk Lamat appears to be around Alisaie's age.

Which means she's actually around 16/17.
