Invasion Earth

20,000 years ago they attacked our origin planet of Haven. They drove us across the galaxy, to three habitable planets. We thought we were safe. We forgot. We regressed. We started over. But they never forgot. And then they found us. After destroying two planets populated by humans, they turned their eyes towards Earth. The third and last planet with humans. And from that moment on, we were doomed.

But then there was hope. It came in the form of an avenging angel. Armed with one of the aliens' own powerful weapons. A human, created using DNA taken from the aliens themselves. And raging with hatred for what they had done to her planet.
