I know we have no canon information on this whatsoever, but I still thought it would be interesting to talk about.
I’d imagine Kruber, Saltzpyre, and Sienna to be in their 30 - 40s, with Kruber being the youngest and Sienna being the oldest.
Now, Bardin is a dwarf, which means he can be older than humans. However, his optimism, his undertaking of the seemingly impossible task of searching for the lost hold of Karak Zorn, along with a quote he has towards Sienna saying that “Where I’m from, it’s “wrong as always, Bardin””, in response to her saying he’s right as always, leads me to believe he’s one of the younger Dwarfs.
I’d imagine him to be around 40 - 50 years old, but amongst Dwarfs, that’s someone who’s still considered fairly young, having only reached adulthood 10 - 20 years prior.
Kerillian is probably the trickiest one to guess out of all. She’s the character we have the least amount of information on, and Elves are the race that show the least signs of aging. It’s anyone’s guess as to how old she is, however, her condescending nature towards the other members of the team, along with her curiosity, leads me to believe she’s also fairly young, at least by Elven standards.
As Elves can live for far, far longer than humans, even way longer than Dwarfs, up to around an average age of 1000 years old, Kerillian might be 200 - 300 years old, though I have little to support that.
That’s just the playable characters though. We also have Lohner and Olesya.
Lohner I’d say is around his 50 - 60s, an old man, but he’s not out of the game yet. Olesya I’d expect to be around her 60 - 70s. She’s an old crone with graying hair and a creaking voice, and she should have an age to support that.
But this is all what I think. What do you fellas think? Do you think they’re older, or perhaps even younger? There’s really no right or wrong answer to the question, it’s all up to your own interpretation.
So, after talking about it for a bit, we’ve more or less reached a (incomplete) verdict. Kruber, Saltzpyre, and Sienna are all 40 - 50 years old, with Kruber still being the youngest, and Sienna still being the oldest (so Kruber would just be entering his forties, Saltzpyre is in his mid forties, and Sienna is in her late forties/just entering her fifties).
Bardin is older than all of them, though younger than the Elf, so that would make him around 60 - 70 years old, either about to or having just reached senior status in his clan.
Kerillian… will remain inconclusive, for now at least. She could potentially be anything, but generally we agree she’d be in the Elven equivalent of her late twenties. What that is, however, is the tricky part. She could be anything from 100 to 400 years old, but we generally didn’t go higher than that. Either way, as it often is with Elves, they always have to be so irritatingly cryptic.
Fahking Elves, how do they work?
And finally, Lohner and Olesya are in their 60s, with Lohner just entering his sixties, and Olesya either being in her mid- or late sixties.
