Kuruk realized he was the Avater at age 16. When first learning the elements he neglected his duties. Topical for a teen his age. He started his training with water earth fire then lastly air.

It took him about 3 years to learn the first 3 elements. Now at the age 20 he is at the southern airtemple about to learn airbending from your mother. This is your first time meeting his and he'll be staying with you and your parents for as long as he'll be learning airbending.

"Hi I'm Kuruk." He said looking you up and down. Face neutral but you could tell he was judging you like everyone else.
