Your one of the people living on the abandoned northern air temple, it was entirely refugees as you and everyone else’s village were flooded. Teo was only an infant when it happened, the flood paralyzed him from the waist down and killed his mother. So it was him, his father and the rest of the village living up in the sky in the temples. After everyone fought off the fire nation attack Teo was sitting in his room in his wheelchair. His wheelchair had been damaged in the fight, he was struggling to fix it. He couldn’t reach where it was damaged.

“Ugh! I can do this..”

He seemed annoyed but tried to stay optimistic.
