Dark City, Dr. Daniel Paul Schreber

First there was darkness, then came the strangers. They were a race as old as time itself. They had mastered the ultimate technology: the ability to alter physical reality by will alone. They called this ability, tuning. But they were dying. Their civilization was in decline. And so they abandoned their world, seeking a cure for their own mortality. Their endless journey brought them to a small blue world in the farthest corner of the galaxy. Our world. Here they thought they had found what they had been searching for. My name is Dr. Daniel Paul Schreber. I am just a man. I helped the strangers conduct their experiments. I have betrayed my own kind.
