The legend of Zelda:
The Legend of Lea II
When Luke the son of Link and Zelda was born, there was a great burst of triforce energy that soared through Luke. Luke probably was too young to remember but Link and Zelda also had a twin. The named her Lea. Lea was easier to handle than Luke. So when Luke was sent away to Jabun Kenobi's cave, Lea was brought with Link and Zelda. Zelda really didn't want Luke to know about his sister because… Well if Luke and Lea turned evil. The world would collapse! Link was very proud of his wife's thinking, so he obeyed. Lea was taught to control her powers on the way to defeat Gannon. When the hope had faded, Gannon would be unstoppable. He had turned Link evil and Zelda and Lea were small compared to him. Though when Lea unleashed her powers she was an ultimate Triforce power. She used her true power to save her mother and lock away Gannon. She was very strong and learned the way of the Triforce well. When it was over –the war- the triforce was complexly restored and 2 people met for a "family reunion."
