Sevara

In a future so distant it looks like our past, Sevara has seen centuries come and go like so many sunrises and sunsets. After Sevara and a group of shapeshifting immortals guide humanity to peace, one final task remains - to give up their memories, and their immortality, and live one last life. All they have to do is sleep for ten thousands years, and forget. All the immortals keep their promise and give up their powers. Everyone that is, except Sevara. Sevara awakens to find that suffering and cruelty returned to the world, while all her friends have had their memories wiped clean. You'd think that being the only shapeshifting immortal would be a good thing. But Sevara soon finds that the memories of her mortal life infected humanity while she slept, and her very own past may destroy the future.
