Due to the 46th Earth King's lack of popularity, a highly capable warlord from the northwestern Earth Kingdom, Chin, was able to launch a military campaign, plunging the entire Earth Kingdom into civil war; only Kyoshi's peninsula and Ba Sing Se remained under the Earth King's dominion. When Chin threatened Kyoshi's peninsula, Kyoshi used the Avatar State to split her home away from the peninsula, creating Kyoshi Island. In the process, Chin fell to his death when the edge of the newly created cliff crumbled under his feet.
