Thousands of years ago, alien beasts invaded, and the continent of Azeroth was completely changed.
Human beings cannot directly release spiritual energy. They can only construct all races into cards and borrow cards to fight.
Yesin, a card-carrying apprentice, is an ordinary Orion boy from a village on the border of Sedar City.
He has only one goal: to keep his sister alive.
What he doesn't know is——
My sister's illness is not a disease.
His ability is not his talent.
The parents left behind more than just a name.
And the truth of this continent is far more cruel than people think.
