The Hundred Years' War has come to an end. The world has been separated into four nations: Terria, Aquor, Flaro, and Aibo. Due to events during the war, the Terrian government has completely taken over Aquor and Flaro and killed almost all the fire and waterbenders in the world. There are two left. 

Taehyung and Seokjin have been on the run for years. Living off of fruit and the occasional fish caught by Seokjin in the sea, they've been traveling from place to place in order to avoid capture by Terrian soldiers. After escaping the soliders once again in Aibo, they decide to make a visit to Terria's biggest city: Crystal City. It is there when Taehyung and Seokjin realize they are the last two benders of their kind, and they are responsible for ending Terria's rule over the two countries. 

Will Taehyung and Seokjin successfully overthrow the Terrian government? Or will they face being on the run for the rest of their lives and eventually being captured and executed by the Terrian Soldiers?
