When I ordered my copy of Way of Kings from Brandon Sanderson's site, I asked for my personalization for any trivia on Axies or the Aimian in general since Axies was my favorite of the interlude characters; well I got my book today, and Sanderson did not dissapoint with the tidbit he gave me which was, "Axies is basically immortal because of an interaction with the magic. He's basically one of 2 kinds of Aimian."
I hope this means that Axies shows up again in the story, I know Sanderson has said most the interlude characters were just there to show off the world's scope, but Axies with his 'curse' and now his apperent immortality strikes me as perhaps a bit more improtant than just a one off character.
