She was a human, and she lived in the third dimension. She was unaware of the existence of higher dimensions, where more intelligent species lived. She was happy with her life, or so she thought.
He was a zetan, and he lived in the fifth dimension. He was aware of the existence of lower dimensions, where less intelligent species lived. He was bored with his life, and he wanted some entertainment.
He found her, through a device that could scan and manipulate lower dimensions. He was fascinated by her, by her appearance, her emotions, her actions. He decided to play with her, to influence her, to experiment with her.
He changed her, without her knowing. He altered her memories, her feelings, her choices. He made her fall in love, he made her break up, he made her suffer. He enjoyed watching her, laughing at her, controlling her.
He broke her, without any remorse. He destroyed her sanity, her happiness, her life. He left her alone, he left her broken, he left her dead. He moved on to another, to a new toy, to a new game.
He never knew her, but he never cared. He had no empathy, no compassion, no conscience. He lived his life, but he did not live. He was one of the many abusers in the higher dimensions.
