Gan Jin

The Gan Jin are an Earth Kingdom tribe that appeared in "The Great Divide", they have a clean and sophisticated appearance and snobbish attitude as opposed to the dirty and slobbish Zhang tribe; with whom they share a mutual enmity, due to an ancient wrong a hundred years ago...

History
The tribe are refugees of the great war. They are heading away from the Fire Nation to the safety of Ba Sing Se. However, the route to the Earth Kingdom capital takes them through the largest canyon in the Four Nations, the Great Divide.

The Gan Jin tribe has long been conflicting with the Zhang tribe. Tribe lore holds that while their founder, Jin Wei, was carrying a Sacred Orb necessary for the tribe's ancient Redemption Ritual, he was attacked by Wei Jin, founder of the Zhang, who stole the orb.

During the journey through the Great Divide, the Gan Jin were forced to travel alongside the Zhang tribe, who were also en route to Ba Sing Se. However, the two tribes continued to travel in separate groups. Avatar Aang and his friends escorted the two groups across the canyon, and Aang was able to settle the dispute between the two tribes by revealing to them that Wei Jin didn't steal the orb from Jin Wei. However, that was just an elaborate lie since Aang chose to act without proof of what actually happened.

The Gan Jin adorn white and gold robes, and condemn uncleanliness. They are both more cultured and tradition-bound than the Zhang.
