Five years have passed since the Hundred Year War ended, and the world is finally beginning to heal. The scars of the past remain, but hope is slowly taking root. Avatar Aang and Katara are working alongside leaders from every nation to establish a new city where people of all backgrounds can live together—a place that will one day become Republic City. Sokka has grown into one of the world’s greatest strategists, Toph is laying the foundations of a metalbending academy, and Fire Lord Zuko continues the difficult work of rebuilding a nation once feared by the world.
