With a shift in the world's energy due to Harmonic Convergence, Korra and her allies set out to scour the Earth Kingdom in search for the new airbenders to offer training and guidance. However, while the Air Nation is slowly being rebuilt, Korra is faced with a new danger when Zaheer and his fellow Red Lotus accomplices escape their respective prisons and set out to bring all the nations down and succumb the world into anarchy. Their belief that disorder is the natural order poses a lethal threat to Korra, and she must fight to save not only the balance of the nations in the world, but also herself and the Avatar Cycle.
