@Akayaofthemoon Hm, that could work. I was thinking either that or they meet with the party after things are already going. Like, they witness the group being attacked and jump in to help.
So hey, I've been watching Undertale Let's Plays and I've been thinking. If I was in Frisk's position I totally would have let Papyrus catch me, and when it was time for for to eat I'd throw his spaghetti out and be like "You have to bring me steak and beer, it's all we eat on the surface!"
@pyrak In the case of your second character, I think it would make a lot more sense for it to be his grandfather who gained airbending than his father. Other than that, as long as I can trust you to give your characters their own minds and not blatantly use them as a single character, they're in.
@pyrak Well, I've been thinking about having the Avatar world be at the early stages nuclear-equivalent technology and the advancement of spirit vines as an energy source would fit in with that pretty well. I don't know if anyone will have developed weapons of mass destruction yet, but there will definitely be some stuff powered with spirit energy.
@pyrak HM well you're more than welcome to have at least one. We haven't talked about it much yet but since I kind of already gave my co-GM the okay to have two characters I guess I can't see anything wrong with letting players do it. My only concern is the possibility that I might be putting too much power into the hands of one player.
