That day, the sun set as usual.
But it never rose again.
The world turned black, and not even light could pierce the darkness.
People built seven cities in the dark, struggling to survive in a world shrouded in black mist.
When they were certain the sun would never rise again, some chose to give up.
Others chose to pass the torch onward.
And a gray tower was rising from the darkness.
"We don't ask for the world to turn white again. But we must put an end to the black, even if all we can do is make it paler, make it gray."
Ten years after the sun disappeared, a boy named Ye Yi found a playing card in the darkness.
The Queen of Hearts.
Ye Yi tried reading the words on the card. It lit up.
Its light even drove away the black mist that blanketed the world.
