The Hand That Rocks the Cradle

AU: Aang was never found in the iceberg by Katara & Sokka, but by the Fire Nation instead. Firelord Ozai adopts Aang as his son, a Prince of the Fire Nation, with hopes of using the Avatar as his Weapon — after all, the hand that rocks the cradle, rules the world. Aang has mastered all the elements but one. What will happen when a certain waterbender is brought in as his teacher?
