It made me think "Just how old is Brayflox?".

Probably middle-aged, by our standards? She's got a daughter, and despite the general dilapidated state of the Hinterlands, it hasn't been abandoned all that long. Y'shtola was born and raised there, and she's only in, what, her 20s?

Actually, the archons have to all be in their 30s at least, since they first arrived in the city-states 15 years prior to ARR, and they looked exactly the same age then as they did in ARR. In one of the Tales from the Calamity it is mentioned that Thancred claimed to be 18 I think at that point, which would make him 33 in ARR. Of the main 4, I think from oldest to youngest it's probably Papalymo, Y'shtola, Thancred, Yda.
