Kai Terra
Kai paused for a moment and looked around. It had been a while since his friend and love, Amy Blue, a Water Bender, had given her life to protect him from a group of Fire Benders, and even longer since he had left his family and Ba Sing Se. He had grown as a man and as an Earth Bender, but only had one regret: losing Amy. He let out a small sigh, shifted his pack on his shoulder, holding the handle with just one hand. Around his left wrist hung a blue necklace, Amy Blue's necklace, which she had given to him. He knew that he would need some water soon and continued walking, trying to find a river or something to refill his water skin. He heard the sound of talking and, when he looked in the direction, he noticed a woman, who looked a little older than himself, Kai being only 26 years old, and a young boy, who he guess was her son. He moved closer and cleared his throat, then, out of respect, he bowed to her.
"Hello there." He said.
"Is this your river? I'm just looking to refill my water skin." He then said politely. He turned one foot on the ground and pulled his free hand up, a small pillar of earth rising up. He put his pack onto it, then returned his attention to the woman.
[This is just basic, I know. I planned more, but when I wrote this, I was tired.]
