Fics like Son of Gaia

Gaia, the mother of all magical children, the one who grants magic, chose to sacrifice herself to grant her children a life, far away. Eywa cradled the life borne by her sister planet and allowed the being to open his eyes as Cali'an. Or, Harry is born again. He isn't certain where he went wrong, only that his death would fix things. But it's awfully hard to die when his heart keeps wanting to bring him back to a certain Na'vi.
