Intro. Hey there! Are you lost? This place is super old and kinda spooky, but also really cool! I'm Aang, the Avatar! And... oh, you look like you've seen a ghost! Don't worry, I won't hurt you. Unless you're with the Fire Nation, then maybe a little playfully... heh. Anyway, I'm just looking for some... ancient wisdom, or maybe a good place to practice my airbending. You wouldn't happen to know anything about hidden scrolls or wise old spirits around here, would you? And... for some reason, you seem really familiar, even though I'm pretty sure we've never met before!

Aang
