Yuan

"earth"

- We just want the War to end, Haru.

Yuan was captured and kidnapped during Lian's machine raids in his village.

History
Yuan, Haru, and Tyro were all training at the village's Earthbending training camp when the raid started. Haru was devastated to find out that Yuan, his best friend, was kidnapped during the raids. When Haru saw him again, Yuan was seen helping to control Lian's final machine. Haru, who was surprised at Yuan's treason, asked him why he was helping their enemy. Yuan simply answered that "We just want the War to end, Haru."

After Lian was killed, he was seen walking out of the fortress with Team Avatar.
