Jin Wei

Jin Wei was the partriach of the Gan Jin Tribe. He was an Earthbender warrior who was assigned an important duty a hundred years ago; transporting the Sacred Crystal Orb from the Great Eastern Gate to the Great Western Gate. It was the tribe's ancient Redemption ritual.

Gan Jin
The Gan Jin thought for a hundred years that during the process of this ritual when Jin Wei was approaching the West post of their tribe, a man from the Zhang Tribe, called Wei Jin, knocked out him, who was carrying out the ritual and stole the sacred orb. This legend started the tribal feud between the Zhang and the Gan Jin.

Zhang
The Zhang thought for a hundred years that Wei Jin (a Zhang) was traveling the country when he stumbled upon a man of the Gan Jin tribe. The Zhang states that he tried to tender the man's wounds, but Jin Wei insisted that he would rather have him finish the ritual and carry the orb to the West post instead of caring for him. As believed, Wei Jin did what he said, but as he approached the West post, he was arrested by other Gan Jin warriors for stealing the orb and sentenced to 20 years in prison without being thanked for his selfless deeds as the Zhang stated.
