Malu arose as a figure of Earth Kingdom legend in the years following the Fire Nation's first strikes. An enigmatic beauty who supposedly controlled the spirits and seemingly vanished and appeared at will, Malu was truly an airbender whose mother hid her in a mountain cave to escape the Fire Nation's storming of the Eastern Air Temple. Her parents were airbending monks and some of the Hundred Year War's first casualties. For years, she lived a solitary existence in the forest, but, ten years into the War, she stopped hiding and began attacking Fire Nation soldiers. Despite not having a teacher under whom to train, she quickly mastered the airbending skills that helped her survive for so long.
Afterward, some say she made her home in the mountain passes, and villagers paid tribute to the spirit who protected the forest so long ago.
