The Avatar is the protector of the world, and the only being who can master all four elements. Fire, air, water, and earth. Throughout the Avatar's life they have many teachers, but some Avatars are blessed with the best teacher they could ever ask for. The Lavisar.
The Lavisar occurs once every couple of generations, born of the same element of their Avatar. They are a guide, advisor, and guardian. Granted with wisdom far greater than some spirits, and the courage and strength of an entire army.

Hekima is an airbender. She's a wildcard and a daredevil, with a side of sarcasm and a hint of wisdom far beyond her years. She mastered airbending at the age of thirteen, two years later, her little brother figure, Aang, mastered it at twelve. They've always been inseparable, hardly ever fought. No matter what anyone did, you couldn't break their connection and their undying love for eachother. Hekima would go to the ends of the Earth for him.
*does not bend multiple elements*
