Heya, I've just started playing the game and it's honestly looking really great so far. I do have one question that I can't seem to find specific info on in the comments or in game. I've been wondering how old all the true wyvarians are? If it's meant to be a reveal later on or spoilers than I can completely understand.
We wanted to hide the exact age of all the villagers until the end, but you can assume the dateables are about 20-40 ish (I don't think I need to specify who the oldest one is). This is mostly so we can be sure of the timeline of events since we are also working on backstories and info about them in the background.
True Wyverians, in general, do age slightly longer than humans, up to 150 years. The explanation can be found in the logbook which you can check it out anytime.
