Kaja

"fire"

- Looks like we have a lot more training to do. . . after you rebuild the temple.

Kaja was a Fire Sage during the time of Avatar Roku and was the one who helped him master Avatar State.

History
Kaja's early history is unknown, but at some point during his life he became a Sage. When Avatar Roku needed to master the Avatar State, Kaja was chosen as the one to help him accomplish this. Roku managed to get into the State after five months with the power of the summer solstice sun, but he became trapped in it and could not control his actions, destroying most of the temple. Kaja eventually managed to get him out, and made him rebuild the temple. Soon after, Roku managed to master the Avatar State and Kaja's job was finished.

At some point, Kaja fathered a child who eventually gave birth to his grandson, Shyu.
