In 1000 AD, Dumbledore became the new consul of Westeros. In order to curb the influence of the Wizengamot and Duke Slytherin in the army, he hoped that Sir James Potter of the West could go to King's Landing to become a tribune. Even though he knew the road ahead was dangerous, James was still determined to help his old friend. Before leaving, he awarded the Gryffindor sword Dawn and the crown to his fifteen-year-old eldest son, Harry, so that he could act as the lord;
At the same time, Duke Slytherin had a dream: In the ice field, a dark stag rushed towards him. It dragged the shadow of a lion and roared into fire. Then a red dragon emerged from the fire and burned him with dragon flames...
This reminded him of a prophecy many years ago: the lion died and the deer was injured, the poisonous snake coiled its nest, and the magic dragon appeared in the world.
Concept: HP's story takes place in a world of ice and fire
