Look at the palm of your hand. Do you have a mark like this? If so, the fate of the world may be in your hands.

Long ago, the evil Zero invaded the world, bringing endless calamity. To protect humanity, people bearing marks on their hands fought Zero to the death and eventually sealed Qiongqi, King of Ten Thousand Zeros. They forged their vows and dreams into long feathers, then spread their wings and flew toward the unknown. They were called the Xialan.
