Oooh, interesting prompt!
Hmm... Well, Alasdair is a pretty cautious lad and tends to stay well away from danger if he's able, so he probably has a better chance of having a long life than some. That said, he does have a strong protective instinct, so there's a decent chance that he might end up dying while protecting somebody. But storywise, I'd rather that he live long enough to go back to his family and to fully forgive himself, however long that might take. He's not looking for some grand or glorious ending, and I'm not really looking for that either.
Faran... Again, she doesn't really get into a lot of fights, but she's way too curious and impulsive for her own good sometimes. Probably she would die from poking her head into someplace she didn't belong (honestly, I'm just glad she's not gone poking around the Rift yet... much.), or from getting in a fight with someone she thought was a bully, and didn't pay attention to the fact that they were bigger than her and more heavily armed, so. As far as what I would be interested in, I think it's kind of the opposite of Al - I think it would be cool for her to meet her end while on some grand adventure or making a great discovery or something.
