May the importance of these feelings rise to Heave

Well, Aang is tired after playing with his three kids.

*clockwise from top: Kya, Tenzin, Bumi.
*I don't know how old the kids are older from each other.
*Kya's hair is gray because I though it'd be nice. Maybe Yue wanted to bless the first son of Aang as a thanks-for-helpeld-me-save-my-tribe gift.
