[This story takes place after the end of Book 2 of The Legend of Korra, and will span until after the end of Book 4.] The world is a different place now: spirits and have now started to live together again after 10,000 years of separation. One of the effects of the Harmonic Convergence has been the rebirth of Air benders all over the world, regardless of origin. Rakkim, a fire-bender and Nim, a newly realised Air bender, travel the world in search of knowledge and adventure. Once their paths cross, their lives will forever be changed.
