Jumper

In the beginning of time, the Humans weren't the only ones.
The Haru, a life form similar to the Humans, roamed the Earth. They looked the same in appearance, but the Haru were further developed. They were stronger and had special abilities that the Humans didn't have. Their minds had more power.
The Humans were larger in population, and claimed that they were the true rulers of Earth.
Because of this, many Haru grew arrogant and decided that they, being superior, should be the ones in control.
The ones who did grow arrogant were full of anger and hatred, becoming evil. Because of the power their minds had, their hatred became so strong that it changed their race. They were no longer Haru, they were Idalys, a powerful race that was an evil and hateful form of the Haru. They sought to kill the humans and gain control of the Earth.

Because of this, the Haru's intentions changed from living a peaceful life to saving the Humans. They split into tribes across the planet, and raised their people to become Palibars, or Protectors, that protected the Humans. To protect the humans, they had to kill the Idalys.

Because of this, the Idalys had to kill the Haru who stood in their way and the Humans.

Robyn, a Palibar in training, withstands a horrible tragedy, losing everyone she loves. She seeks out to join the tribes and kill the Idalys as a whole.

Along her journey, she witnesses many more tragedies, overcomes plenty of hardships, and stumbles upon the worst that life can present.
