[Wan accepted the card, recognized the numbers as a phone number. But he didn't exactly have a phone... The world needed an Avatar, though. Wan didn't even have a formal address. He'd been happy so far just keeping mostly to himself. Living in the wilds. But he wasn't exactly easy to reach there. And the world had changed so much that being able to reach the Avatar was kind of important to it. If he and Aang were needed, they should have the ability to be contacted easily.

He stared at the card for a few long moments before he closed his eyes, sighed, and dropped his head.]

I live in the wilds. And I don't have a phone. Or a proper address...

And there's nothing there that has given me any answers, but if you find something, just ask the spirits to find me. They'll come get me. Most of the spirits that are around the city know who I am. So, even if you're not in the wilds, you should still be able to get a hold of me.
