The story

A century ago, the world changed. Everyone can awaken the power of an ancestor. The older the ancestor, the stronger you become. On his first awakening, while others became mere warriors, he made a legendary choice. Now, as they all think he's reached his limit, he prepares for a second awakening... then a third. How far back in time can one man truly go?
