Yi

The State of Yi is one of the constituent states of the Earth Kingdom. Though the state is mountainous and rural, it has significant mineral wealth. After the death of Earth Queen Hou-Ting and the kingdom's descent into chaos, Yi fell prey to roaming bandits who terrorized the local population and caused severe damage. This eventually forced its governor to pledge his allegiance to Kuvira in return for protection from the bandits, dissolving the state in the process.

History
After the kingdom's descent into chaos, the state of Yi fell under siege of hundreds of bandits, leaving it in a critical situation with its supplies cut off, the governor contacted Tenzin to receive help from the Air Nation.

In 174 AG, Opal and Kai arrived in the governor's city and drove off three bandits. He was pleased to see them, though wondered where the rest of the airbenders were. He was shocked to learn that the two teenagers were all Tenzin was able to send as there were hundreds of more bandits threatening to cause Yi to collapse.

Not long after, Kuvira arrived in Yi with her army, prompting the governor to ask what she was doing there. At her request, he went on board her train to have a private conversation. Despite the imminent risk of collapse, the governor refused to sign Kuvira's offer in which she would receive access to all of Yi's resources, especially its rich ore supply, in return for complete protection. He ordered her to leave his state and angrily left the train after being intimidated by the army commander.

After Opal and Kai tried but failed to gather supplies from the villages surrounding Yi's capital via the sky, the governor realized that the people of Yi's situation was hopeless and signing Kuvira's contract was his only choice. After Kuvira brought supplies of food and mecha tanks into the capital of Yi, the governor was forced to pledge his loyalty to her and make her the ruler of Yi if he wanted to keep his position as administrator.
