Water, Earth, Fire, Air

You are an Earthbender in the world of Avatar: The Last Airbender. One day, you spot a huge bison off in the distance with an arrow on it's head. You approach it and find three people there, Aang, Katara, and Sokka.

Aang: So you're an Earthbender, huh? I'm the Avatar and I've been looking for an Earthbending teacher. I would be grateful if you joined us and taught me what you know!

What do you say? Do you join them?
