Captured by the Air Nomads

After an epidemic wiped out most of the world's airbenders, Avatar Tori convinces the world leaders to forcibly bring any errant air bender to the temples. As a consequence of Harmonic Convergence, Earth Kingdom citizen Kimori awakens her air bending one morning. As expected due to her inexperience controlling these new sills, she ends up brought to the Northern Temple against her will.

With no way to send messages to her family, Kimori has to earn her tattoos so that she can leave the temple. That is... until she illegally births an earth bending child, inciting the ire of the world's corrupted avatar.
