Alright, just a bit of a problem. I know I said take liberties in this world, however there wasn't exactly a war that destroyed everything. And if there was, even if he were 100 he wouldn't have been able to fight in it. I probably should have mentioned something about the past but yeah, that's the idea. Unless there was a small battle somewhere for something else (land or territory), but nothing huge as this world didn't end in a blaze.

Also it's a little odd for someone so much older to be joining this particular group. Not that there's anything wrong with having an older character, I'm just thinking he's probably too seasoned to even need them. Especially since Carter and Edgar are so much younger.

You also missed filling the section about why he would even be with this group in the first place. And have you read the rules?
