A 14-year-old boy and a 50-year-old man from a planet hundreds of light years away from Earth suddenly hear the bamboo door of their hut shaking. A long sword, clearly made of metal not found on Earth, cuts through the door and into the man’s chest. Before he dies, he tells the boy to run.

The boy runs straight through the wall and into the jungle, running at around 60 miles per hour. Both he and the creatures chasing him have supernatural abilities. The boy makes a nearly impossible leap across a ravine and believes he’s escaped his pursuers. Suddenly, a supernatural being called a Mogadorian grabs him and tears the amulet off the boy’s neck. The amulet protects him and his kind, known as Legacies, and the only weapon that can break the protective charm is the white metal sword. Before the Mogadorian kills the boy, the boy looks into his eyes and tells him that the Legacies live, and they will find each other and together destroy them. The sword bursts into silver flames and strikes the boy dead.
